Question 169218: Have trouble understanding sequences, can anyone give assistance?
Find ratio, r, the general term, a(base-n), and a(base-11)
2,-6,18,-54,162,...
Answer by Mathtut(3670) (Show Source): You can put this solution on YOUR website!
t(n) = a[r^(n-1)]
where
t(n) = 'n'th term
a = first term of the sequence
r = common ratio between two successive terms
Here a=2, r=3
hence you get 2,-6,18,-54,162...
