Moderate -0.8 This is a straightforward application of the sum to infinity formula requiring recognition that multiplying each term by -2 multiplies the sum by -2. It's a single-step problem testing basic understanding of geometric series properties, making it easier than average but not trivial since it requires understanding how transformations affect sums.
3 A geometric sequence has a sum to infinity of - 3
A second sequence is formed by multiplying each term of the original sequence by - 2 What is the sum to infinity of the new sequence?
Circle your answer.
The sum to infinity does not
