More information needed.
Is this geometric sequence or arithmetic sequence? Some other kind?

Trying for arithmetic sequence, and first term = 4,
4%2B%28n-1%29%2Ad=108 if n=5,
4%2B%285-1%29%2Ad=108
4%281%2Bd%29=108
1%2Bd=108%2F4
1%2Bd=27
d=26

The general term seems to be highlight%284%2B%28n-1%29%2A26%29 and you can use this to find for when n=6.
