Since no options are given here, so there can be numerous logics for solving this problem.
The very first and simple operation will be adding the digits and analysing the resultant series.
1+3, 1+7, 2+3, 3+7, 7+3 = 4, 8, 5, 10, 10
We can see in the first four numbers form an alternate patern of twice the preceeding. But the last sum doesn't follow it.
It must be 6. like: 4, 8, 5, 10, 6, 12..........
So, acc to this logic "73" is odd one out.
