2, 4, 8 are consecutive terms of a:
AArithmetic progression
BFibonacci sequence
CSequence of primes
DGeometric progression
Answer & Solution
Correct answer: D. Geometric progression
1. Each term is double the previous one.
2. A constant ratio marks a G.P.
3. So 2, 4, 8 form a geometric progression.
