Note that we can write any odd number as 2n + 1.

So the first one is 2n + 1  - the least

The next is 2n + 3

The third is 2n + 5  - the greatest

So we have (2n + 1) + (2n + 5) = 4n + 6

4n + 6 = 110     Subtract 6 from both sides

4n = 104     Divide by 4 on both sides

n = 26

So 2(26) + 1 = 53

And 2(26) + 5 = 57

And 53 + 57 = 110
