alleryAn arithmetic progression is a sequence in which the difference between consecutive terms is
AA constant
BDoubling each time
CSquared each time
DAlways negative
Answer & Solution
Correct answer: A. A constant
1. AP means an arithmetic progression.
2. Consecutive terms have a fixed difference d.
3. If terms are a1, a2, a3, ... then a2 - a1 = a3 - a2 = d.
4. So option A is correct.
