Question

Given that an = 3an - 1 + 1, where a1 = 2, find the 3rd-6th terms of the sequence.

Answer 1

D) 22, 67, 202, 607

Explanation:

Answer 2

For the answer to the question above, if
a1 = 2,
then
a2 = 3a1 + 1
a3 = 3a2 + 1 = 3
Then, we can finally solve for terms of sequence.
(3a1 + 1) + 1 = 9a1 + 4 = 9(2) + 4 = 22

So the answer to your question is,
22, 67, 202, 607

I hope my answer helped you. Have a nice day!
