I think the easiest thing to do is simply eliminate choices:

a) 9 = 5 + 3 + 1 (OK)
b) 10 = 7 + 3 (OK)
c) 12 = 7 + 5 (OK)
d) 13 = 7 + 5 + 1 (OK)
e) 14 = ???

The answer is E.

I think any "mathematical" way of solving this would just take longer and is unnecessary (unless someone can prove me wrong?)

Picking number is the best technique for this example

It took me 20/25 seconds to choose E.

The only way to solve this is to run quickly through the numbers.

I have read suggestions that have said for questions where you are backsolving, start from E and work backwards.

E. 12:
No combination of those numbers 1,3,5,7 can add up to 12
1+3+5+7 = 16
16-1 = 15
16-3 = 13
16-5 = 11
