Hello, CPR!
I'm not familiar with "backtracking".Find the explicit formula for the recursive sequence using backtracking:
. .
I’m thinking I will have: .
This is a geometric sequence with first term , common ratio
The general term is: .
Find the explicit formula for the recursive sequence using backtracking
d1 = 3
dn= -2dn-1
I’m thinking I will have (-6, 12, -24, 48,…..)
dn = -2dn-1
= -2dn-1 + 1
= -2 (-2dn-1 +1) +1
but I do not know what else to do to end with a formula. Please show me what my formula will be
* all the (n-1) should be subscripts, do know how to get it to subscript here in this window
