Question

Find four consecutive negative integers whose sum is -42

Answer 1

Answer: -12, -11, -10, -9

Explanation:

they all add up to -42

Answer 2

-12, -11, -10 and -9 add up to -42

Explanation:

We can solve this by expressing all four of those integers relative to the first one:

`x + (x + 1) + (x + 2) + (x + 3) = -42\\4x + 6 = -42\\4x = -48\\x = -12`

so we know that the lowest one is -12, and the other three are sequentially higher value:

-12, -11, -10 and -9
