The sum of three consecutive numbers is 72. what is the smallest of these numbers?

If n stands for the smallest number, then the second and third number would be (n + 1) and (n + 2)

Write the equation based on what are given
the sum of three numbers = 72
n + (n + 1) + (n + 2) = 72

Then, solve the equation
n + (n + 1) + (n + 2) = 72
3n + 3 = 72
3n = 72 - 3
3n = 69
n = 69/3
n = 23

The smallest number is 23

29. because you will divide each number of months by 12 to find the number of years. which would mean, 5, 12.5, 16, 45, 50, 72.5. which is crazy. anyhow, i think you find the median in the middle. and yea hope your test goes good
