Solution

$G i v e n, a = - 2 a n d d = 0$
Let the group of numbers be $a_{1}, a_{2}, a_{3}, a_{4}, a_{5}, \dots$
$a_{1} = a = - 2 a_{2} = a_{1} + d = - 2 + 0 = - 2 a_{3} = a_{2} + d = - 2 + 0 = - 2 a_{4} = a_{3} + d = - 2 + 0 = - 2$
Therefore, the series will be - 2, - 2, - 2, - 2, …
Hence, the first four terms of this A.P. are - 2, - 2, - 2 and - 2.
