Three cosecutive odd numbers are such that seven times the the smaller , sutracted from the bigger gives 144 find the tow numbers 
Is it 2 or 3 CONSECUTIVE INTEGERS? You start out saying it's 3, but then go on to talk about SMALLER and LARGER/BIGGER, which indicates just 2, and furthermore,
the question does ask for the TWO (sic TOW) numbers.
If it's 2, then the results, based on what you gave, won't produce INTEGERS, and from what I can recall, ODD NUMBERS are INTEGERS.
If it's 3, then info is missing!
Do what you need to do, if you REALLY need help!
