Let the FIRST number be  (2x + 1)     I put it in this form to be sure the answer is an ODD number

The SECOND number woud then be  (2x + 3)

The THIRD number would be (2x + 5)

 

Add these three terms together to get 117

 

(2x+1) + (2x+3) + (2x+5) = 117    then solve for 'x'

6x + 9 = 117

6x=108

x=18         BUT remeber the FIRST number is (2x+1)    so the first number would be  37     then 39   then 41
