First term = -2
Common difference = -2
So , first term = a
i.e, a = -2
Second term of an AP = a + d
-2 + ( -2)
-2 -2 = -4
Third term of an AP = a + 2d
-2 + 2 × ( -2)
-2 - 4 = -6
Fourth term of an AP = a + 3d
-2 + 3 × ( -2)
-2 - 6
= -8
Option (C) is the correct answer .
Common difference = -2
So , first term = a

Second term of an AP = a + d
-2 + ( -2)
-2 -2 = -4
Third term of an AP = a + 2d
-2 + 2 × ( -2)
-2 - 4 = -6
Fourth term of an AP = a + 3d
-2 + 3 × ( -2)
-2 - 6
= -8
Option (C) is the correct answer .

The first four terms of an AP whose first term is -2 and common differ...
Solution:
Given that the first term of the AP is -2 and the common difference is -2. We need to find the first four terms of the AP.
Let us use the formula to find the nth term of an AP
aₙ = a + (n-1)d
where a is the first term, d is the common difference and n is the number of terms.
Using the formula to find the first four terms of the AP:
a₁ = -2
d = -2
a₂ = a₁ + d = -2 - 2 = -4
a₃ = a₂ + d = -4 - 2 = -6
a₄ = a₃ + d = -6 - 2 = -8
Therefore, the first four terms of the AP are -2, -4, -6, -8.
So, the correct option is (C) -2, -4, -6, -8.
Hence, the answer is option (C).
