alleryIf an AP has first term $a=6$ and common difference $d=-3$, which of the following is the correct AP?
A$6, 9, 12, 15, \ldots$
B$6, 3, 0, -3, \ldots$
C$6, -3, -6, -9, \ldots$
D$6, 3, 1, -3, \ldots$
Answer & Solution
Correct answer: B. $6, 3, 0, -3, \ldots$
Starting from 6 and adding $-3$ repeatedly gives $6, 3, 0, -3, \ldots$.
**Option A uses $d=+3$, while the others do not maintain a constant difference of $-3$.**
