alleryInserting 4, 16 and 64 between 1 and 256 makes the resulting sequence a:
AGeographic progression
BGeological progression
CGeometric proportion
DGeometric progression
Answer & Solution
Correct answer: D. Geometric progression
1. Each of these numbers is four times the one before it.
2. A constant multiplier is the signature of one kind of progression.
3. Inserting 4, 16, 64 between 1 and 256 makes the resulting sequences in G.P.
4. So the answer is a geometric progression.
