The sum of three consecutive numbers is 477. What is the 3rd number?

160

Step-by-step explanation:

Consecutive numbers have a difference of 1 between them.

Let n be the first number then n + 1 and n + 2 are the second and third numbers. Summing them gives

n + n + 1 + n + 2 = 477, that is

3n + 3 = 477 (subtract 3 from both sides)

3n = 474 (divide both sides by 3)

n = 158

The 3 consecutive numbers are 158, 159, 160

The third number is 160
