The sum of three consecutive numbers is 90. What is the smallest number of the three numbers?
1 answer:
The three numbers are n, n+1, and n+2.
n + n + 1 + n + 2 = 90
3n + 3 = 90
3n = 87
n = 29
The smallest number is then 29.
n = 29
n + 1 = 30
n + 2 = 31
So the three numbers are 29, 30, and 31. Hope this helps! :)
