The sum of four consecutive even integers is 1284, what are these even integers? I can easily tell you that the answer are 318, 320, 322 and 324. You must be interested in how to find these 4 consecutive even integers whose sum is 1284. There are three methods here, let us introduce them one by one below.

1. Find four consecutive even integers whose sum is 1284 by hypothetical method

Assuming that 2 * N is used to represent the first even integer, so the second even integer is 2 * N + 2, the third even integer is 2 * N + 4, the 4th even integer is 2 * N + 6.

Therefore, the sum of 4 consecutive even integers is 1284, which can be expressed by the equation

2 * N + (2 * N + 2) + (2 * N + 4) + (2 * N + 6) = 1284

Solve this equation

2 * N + (2 * N + 2) + (2 * N + 4) + (2 * N + 6) = 1284

2 * N + 2 * N + 2 + 2 * N + 4 + 2 * N + 6 = 1284

8 * N + 2 + 4 + 6 = 1284

8 * N + 12 = 1284

8 * N = 1284 – 12

8 * N = 1272

N = 1272 / 8

N = 159

So, 2 * N = 2 * 159 = 318

Now, we can get that 318 is the first integer of 4 consecutive even integers whose sum is 1284. So, the second even integer is 320, the third even integer is 322, the 4th even integer is 324.

The answer came out, the sum of 4 consecutive even integers is 1284, these three even integers are 318, 320, 322 and 324.

Verify: 318 + 320 + 322 + 324 = 1284. Correct!

This is the most common method, let’s look at the second method, which is my favorite method.

2. Find four consecutive even integers whose sum is 1284 by formula method

According to the consecutive integers calculator based on sum, we can know that the sum of M consecutive even integers is S, the first even integer formula is

First(e) = S / M – M + 1

M represents the number of consecutive even integers.

S stands for sum.

Back to the problem we want to solve: find four consecutive even integers whose sum is 1284. In here, M = 4, S = 1284. Replace them in the formula to calculate the first even integer

First(e) = 1284 / 4 – 4 + 1 = 321 – 4 + 1 = 318

The first even integer is 318, so, it can be easily calculated that the second even integer is 320, the third even integer is 322, the 4th even integer is 324.

Thus, the answer are also 318, 320, 322 and 324. Same as the first method. Then look at the third method, which is the simplest one.

3. Find four consecutive even integers whose sum is 1284 by average method

The principle is very simple, because we want to calculate the consecutive even integers, so after calculating the average, we can find the even integers near the average.

The sum of 4 consecutive even integers is 1284, so, the average of these 4 consecutive even integers is 1284 / 4 = 321. The even integers around 321 are 315, 316, 317, 318, 319, 320, 321, 322, 323, 324, 325, 326, 327. Now the problem is simple, find 4 consecutive even integers from 315 to 327 and their average is 321. The answer are 318, 320, 322 and 324.

So the sum of 4 consecutive even integers is 1284, these even integers are 318, 320, 322, 324. The results are consistent with the above two methods. Is it very simple?

Problems can be sloved by this answer

Now, we have found out these 4 consecutive even integers whose sum is 1284, some problems can be easily solved.

  • The sum of four consecutive even integers is 1284, the smallest one is 318.
  • The sum of four consecutive even integers is 1284, the greatest even integer is 324.
  • The sum of four consecutive even integers is 1284, the average of these even integers is 321.
  • The sum of four consecutive even integers is 1284, the product of them is 318 * 320 * 322 * 324 = 2026482688.
  • The sum of four consecutive even integers is 1284, the sum of their squares is 3182 + 3202 + 3222 + 3242 = 412184.

Summarize

On this page, In addition to introducing three methods how to find four consecutive even integers whose sum is 1284, it also provides a calculator that calculates four consecutive even integers based on the sum. If you encounter a similar problem next time, you can directly use this calculator to calculate the answer, which is very convenient.

Of course, if the problem you encounter is more complicated, such as: the number of consecutive integers is not 4, or you need to calculate consecutive integers or consecutive odd integers. You can use our other more advanced sum-based consecutive integers calculator, where you can specify the number of consecutive integers and select consecutive integers type: natural integers, odd integers or even integers. I believe it can help you.

Well, that’s it, the above are three solutions to find four consecutive even integers whose sum is 1284. Personally, I prefer the second method, because it can accurately calculate the first integer and the calculation process is very simple. So how about you?
