Even numbers must be symbolized as multiples of 2, such as 2x,2x+2,2x+4 etc.

Odd numbers must be symbolized as an odd number more than or less than an
even number, such as 2x-1, 2x+1, 2x+3
-------
Your Problem:
1st 2x-1
2nd 2x+1
3rd 2x+3

Equation:
2x-1+2x+1+2x+3 = 117
---
6x+3 = 117
6x = 114
x = 16
---
1st: 2x-1 = 31
2nd: 2x+1 = 33
3rd: 2x+3 = 35
