Question

Find 3 consecutive even interferes such that their sum is 42

Answer 1

12, 14, and 16

Explanation:

These kinds of problems can be written as the equation x + (x + 2) + (x + 4) = s, where x = first integer and s = total.

Plug in s: x + (x + 2) + (x + 4) = 42

Associative property of addition: x + x + 2 + x + 4 = 42

Combine like terms: 3x + 6 = 42

Subtract: 3x = 36

Divide: x = 12

This means that the first integer is 12, and the rest are 14 and 16.
