There are 3 consecutive odd integers that sum to -57. What is the greatest of these integers?

Question

Please answer i am struggling

Answer 1

Let x be the first odd integer.

Then x+2 is the next odd integer

And x+4 is the next odd integer after that.

The sum of these 3 consecutive odd integers is -57

So x + x+2 + x+4 = -57

3x + 6 = -57

3x = -63

x = -21

so next integers are x+2 = -19 and x+4 = -17, the largest being -17.
