**Reiny**, Wednesday, October 26, 2011 at 5:01pmSince 1 , 4, 13 do not form either an arithmetic nor a geometric sequence,

having only 3 terms is not enough information to see the pattern

e.g. I could claim that the sequence is

1 4 13 40 121 by claiming that I add increasing powers of 3 to get the next term

that is,

1+3 = 4

4+9 = 13

13+27 = 40

40 +81 = 121
