For similar post, see: https://www.beatthegmat.com/iq-i-gues-t270998.html For example, what comes next in this sequence: 1, 2, 4, ... ? Well, perhaps we're doubling each number, in which case the next value is 8 Or, perhaps we're adding 1, then 2, then 3 then 4 (etc), in which case the next value is 7 Yes, I can see that having 5 values reduces the number of possible scenarios, but the rationale for why the GMAT would not test this still stands.

5, 16, 60, 236, 940, 16-5 = 11 60-16 = 44 = 11x4 236-60 = 176 = 44x4 940-236 = 704 = 174*4 So, next digit = 940 + 704*4 = 3756 Is it correct?

Hi sgr21, Brent is correct that this question would never appear on the real GMAT. Also, the 5 answer choices can provide value information (or hints) as to how to solve this problem. The pattern behind this question is to "take a term, multiply it by 4, then subtract 4" to get the next term: 5x4 - 4 = 16 16x4 - 4 = 60 60x4 - 4 = 236 236x4 - 4 = 940 940x4 - 4 = 3756 GMAT assassins aren't born, they're made, Rich
