Write first four terms of the AP, when the first term $a$ and the common difference $d$ are given as follows:
$a = -2, d = 0$

Given:

$a = -2, d = 0$

To do:

We have to write the first four terms of the arithmetic progression formed. 

Solution:

First term $a_1=a=-2$

Second term $a_2=a_1+d=-2+0=-2$

Third term $a_3=a_2+d=-2+0=-2$

Fourth term $a_4=a_3+d=-2+0=-2$

Therefore, the first four terms of the AP are $-2, -2, -2, -2$.
