The sum of five consecutive numbers is 80. Find the largest number.

Question

Accepted Answer

Let the five consecutive numbers be x, x+1, x+2, x+3, and x+4.
Their sum is given as 80:

x + (x+1) + (x+2) + (x+3) + (x+4) = 80

Combine like terms:
5x + (1+2+3+4) = 80
5x + 10 = 80

Subtract 10 from both sides:
5x = 70

Divide both sides by 5:
x = 14

The numbers are 14, 15, 16, 17, 18.
The largest number is 18.
