So do you know the pattern at least?

anonymous · Answer

Do you know the pattern of the sequence? @thebluepilot

thebluepilot · Answer

Not really... I'm kind of frantic cause i'm lost on remembering how to to a geometric sequence.

anonymous · Answer

Okay so clearly we are multiplying by 3

anonymous · Answer

1 x 3 = 3

anonymous · Answer

3 x 3 = 9

anonymous · Answer

So just continue to do that until you get 14 terms. So do that and tell me what you get.

thebluepilot · Answer

So we just go on and on till we reach the 14th term?

anonymous · Answer

Yes. Correct. When you get 14 terms you simply add them all. :) @thebluepilot
