PLS HELP A friend says that the recursive formula for the geometric sequence $1,-1,1,-1,1,is an+1x(-1)^n-1. Explain your friend's error and give the correct recursive formula for the sequence.

For a geometric sequence with recurrence of the form a(n)=ra(n-1) where r is constant, each term is r times the previous term. This implies that to get from the first term to the nth term, we need to multiply by n-1 factors of r.

hii

you are looking so h*t and s**y..

y + 11 = (1/4)(x + 16)
