Write first four terms of an AP when the first term is -2 and common difference is O.​

Explanation:

If the common difference is 0, then we're adding 0 to each term to get the next term. However, adding 0 doesn't change the number. So that's why we have the same thing written four times.

As another example, let's say the common difference was 1 instead of 0. That would mean the first four terms are -2, -1, 0, 1 since we add 1 to each term to get the next one (eg: -2+1 = -1).

-2, -2, -2, -2.

Step-by-step explanation:

If the common difference (d) is 0 then all terms are the same as the first:-

AP = a, a + d, a + 2d, a + 3d

Here we have -2,  -2+0, -2 + 2(0), -2 + 3(0)
