Question

11. The first four terms of an AP, whose first term is -2 and common difference is -2 are​

Answer 1

- 2, - 4, - 6, -8

Explanation:

If the first term of the arithmetic sequence is is -2 , and the common difference is -2, then we can generate the first four terms the following way:

a1 = - 2

a2 = - 2 - 2 = - 4

a3 = - 4 - 2 = - 6

a4 = - 6 - 2 = - 8
