Question

The sum of three consecutive odd numbers in 177. What is the largest of the three numbers?

Answer 1

n + (n + 2) + (n + 4) = 177

In order to find consecutive odd numbers, you simply need to add 2 to the unknown.

For example, if I had the number 1 and wanted to find the next odd number, I could add 2, and that would make the number 3.

Combine all of the numbers on the left side:

3n + 6 = 177

Subtract 6 from both sides:

3n = 171

Divide both sides by 3:

n = 57

The first odd number is 57.
