hi Siva882

Welcome to the forum.

At the moment I cannot see any obvious answer to this. The differences started nicely as 1, 8 , 27 and then that didn't continue. Sequence puzzles can be tough. For any set of numbers you can always fit a formula that will generate the sequence but this is not usually what the puzzle requires. Sometimes they use a single digit from each term to get the next; or some complicated sum using all the digits. We have been asked before for next numbers in sequences and the best efforts of several members have not found an answer. Check you've got the right numbers, please.

The quartic(degree-4) polynomial in *n* satisfying the series for *n* = 1, 2, 3, 4, 6 is:

Just plug in *n* = 5 to find the missing number.

That's very ingenious! Why a quartic?

This was asked in the mock test and was told "?" is 92. When our group tried to do it we didn't get it.
