Can you deduce the pattern and find the next number in the series?
7, 15, 27, 99, __? Pick
A) 276	B) 277	C) 278	D) 279	E) None of these
Solution:   277   Explanation:   7 = (1^1 + 2^1 + 3^1) +1   15 = (1^2 + 2^2 + 3^2) +1   37 = (1^3 + 2^3 + 3^3) +1   99 = (1^4 + 2^4 + 3^4) +1   Thus the next number will be   (1^5 + 2^5 + 3^5) +1 = 277   Answer 277
