Write a recursive formula that generates the terms of the following:
. . .1, 3, 9, 27
t1=1, n>2 --> tn= 3tn-1
is this correct?
You have the sequence 1, 3, 9, 27 ...
t1=1, n>2 => tn= 3tn-1
What is t2? It's undefined so I don't know how to continue.
I think you're supposed to observe that the sequence is powers of 3
1=30, 31, 32, 33, ...
Let t1=1 and tn=3tn-1
Try that and see if it works.
