Question
Write an A.P. whose first term is a and common difference is d in each of the following.
$a = – 3, d = 0$
$a = – 3, d = 0$
✓
Answer
$a = – 3, d = 0$
Let $a_1 = a = – 3$
Since, the common difference $d = 0$
Using formula $a_{n + 1} = a_n + d$
Thus, $a_2 = a_1 + d = – 3 + 0 = – 3$
$a_{3 =} a_2 + d = – 3 + 0 = – 3$
$a_4 = a_3 + d = – 3 + 0 = – 3$
Hence, An A.P with common difference $0$ is $– 3, – 3, – 3, – 3,….$
