How would you solve? how do you figure out how to solve and what are tips for future problems ?

Since each odd (or even) is two greater than the previous number, two consecutive such numbers are n and n+2.

The we are told that the sum of two such number is 100, so we can say:

n+n+2=100  combining like terms on the left side you get:

2n+2=100



to solve, if you were interested...subtract 2 from both sides

2n=98  divide both sides by 2

n=49

So the two odd numbers are 49 and 51

Ibelieve the answer would be 7, 13, 23
