alleryIn a geometric progression, the fixed multiplier between terms is called the:
ACommon radius
BCommon rating
CCommon reading
DCommon ratio
Answer & Solution
Correct answer: D. Common ratio
1. A geometric progression multiplies rather than adds.
2. The multiplier is the same at every step.
3. The first term is a and r is called the common ratio of the G.P.
4. So the answer is the common ratio.
