The sum of 5 consecutive numbers is - 5. What is the largest out of the numbers?

We can say that x is the largest number.

So the sum is x + (x - 1) + (x - 2) + (x - 3) + (x - 4) = - 5

Now solve for x:

x + x + x + x + x - 1 - 2 - 3 - 4 = - 5

5x - 10 = - 5

5x = 5

x = 1

So the largest number is 1.

Check: 1 + 0 + - 1 + - 2 + - 3 = - 2 + - 3 = - 5 so 1 is correct.
