A$a,\ ad,\ ad^2,\ \ldots$
B$a,\ a-d,\ a-2d,\ a-3d$ only
C$a,\ 2a,\ 3a,\ \ldots$
D$a,\ a+d,\ a+2d,\ \ldots$
Answer & Solution
Correct answer: D. $a,\ a+d,\ a+2d,\ \ldots$
1. Each term is the previous term plus the common difference d.
2. Starting from a: a, a+d, a+2d, a+3d, …, which is the **general form of an AP**.
3. (Geometric progressions multiply by a fixed ratio instead.)
