Solve Consecutive Integer Problems

Question

The addresses on the east side of Arthur Ave. are consecutive odd numbers. Two consecutive house numbers add up to 36. Find the addresses of these two houses.

Answer 1

Consecutive odd numbers are separated by 2, so

 

n + (n + 2) = 36

2n + 2 = 36

n = (36 - 2)/2 = 17

 

The 2 street numbers are 17 and 19.
