Question

The sum of three consecutive odd numbers is $63$. Find the numbers.

Answer 1

Consider the first odd number $=x$
Second odd number $=x+2$
Third odd number $=x+4$
Based on the condition
$x+x+2+x+4=63$
By further calculation
$3x+6=63$
$3x=63-6=56$
So we get
$x=57/3=19$
First odd number $=19$
Second odd number $=19+2=21$
Third odd number $=19+4=23$.
