Use the sequence {−1,171,875;−234,375;−46,875;−9375,…} to answer the question. What is the explicit rule that describes the sequence? PLEASE HELP ME

Question

(A) a_(n)=1,171,875(−1/5)^n−1

(B) a_(n)=−1,171,875(1/5)^n−1

(C) a_(n)=1,171,875(−1/15)^n−1

(D) a_(n)=−1,171,875(1/25)^n−1

Answer 1

The answer is B, because each element in the sequence is 1/5 of the previous element.
