With no more effort to explain what you want than what you have provided, why should a well-meaning stranger rake himself over the coals to help you? — Senex Ægypti Parvi, Feb 14 '15 at 09:05
@SenexÆgyptiParvi That seemed a little extreme, but alright. — Daniel W. Farlow, Feb 14 '15 at 09:06

Here is one option:

Take the only number that appears twice in the small circles of a diagram
Add that pair of numbers, subtract one from the result, and put it in the big circle

a) $3+3-1=5$

b) $18+18-1=35$

c) $43+43-1=85$

(+1) For the one option remark and possible explanation. Questions like this bug me...I mean all sorts of answers are possible, but kudos. :-) – Daniel W. Farlow Feb 14 '15 at 09:01
