Question 930466: How do I write the first four terms of the sequence?
a1=1 and a base n = 3a base n-1 for n >= 2
I know that the first term would just be 1 but how do I find the other 3 terms if n cannot be greater than 2?
thank you

You can put this solution on YOUR website!
a%5Bn%5D+=+3a%5Bn-1%5D for n ≥ 2 (a1 = 1)
what this says is a%5Bn%5D describes ALL the other terms (except a1)
a2 = 3
a3 = 6
a4 = 9
a5 = 12
etc...
