Sn=S(n-2)+11, is 633 a term of the sequence?
1). S1=39
Sn=S(n-2)+11 here all the terms would be the seed value is startig value + some multiple of 11
633 = 39 + 11x
11x= 633 - 39, x= 594/11 =54
Hence it is a term
2). S2=43
similarly 633 =43 +11x
i.e 590/11 produces a remainder hence this is not a term

For 2, 633 could be part of the S1, S3, S5... sequence, and since S1 is not specified, 2 is insufficient.
