Find the first four terms of the sequence defined by:
Un = 4Un-1, U1 = 2
I know the steps, but i dont know what U2, U3, and U4. I think i someone explained that to me i will be able to do it.
No. The OP means Un = 4U_(n-1) or, even better, .
You will need to better learn how to interpret poor formatting (which is why users are encouraged to learn basic latex).
To the OP:
Nope, it's not exactly how you wrote it. Please take the time to learn some basic latex so that you can format equations more clearly next time. See here: http://www.mathhelpforum.com/math-help/latex-help/
