2,3,12,17,22,? What comes in the place of '?'

Question

Answer may A) 7 B) 17 C) 27 D) 37 Please give me explanation also

Answer 1

I think the answer is C.

Take the first term from each of the others: 3-2=1, 12-2=10, 17-2=15, 22-2=20.

3-2=1 is a sort of odd man out, but the others seem to be in a sequence, making the next 25, so 25+2=27 must be the next term, which is answer C: 3-2=1, 12-2=10, 17-2=15, 22-2=20, 27-2=25.

It's a weak argument, I know, but I can't think of anything else at present!

Also, if we add 3 (the second term) to each of the others we get 2+3=5, 12+3=15, 17+3=20, 22+3=25.

The next sum would be 30, so since 27+3=30, 27 would be the next number again.
