If a sequence contains only whole numbers, which of these sequences could include the term 27?
erik [133]
Depending on the first term, the sequences
a_n=2a_{n-1}+1
\\
\\a_n=3a_{n-1}
\\
\\a_n=a_{n-1}+6
would work.

If the sequence began at 6, 
a_n=2a_{n-1}+1=6, 13, 27, ...

If the sequence began at 1, 
a_n=3a_{n-1}=1, 3, 9, 27, ...

If the sequence began at 3, 
a_n=a_{n-1}+6=3, 9, 15, 21, 27, ...
