Question

find the first 4 terms of an ap whose first term is minus 2 and common difference is -2

Answer 1

a ( first term ) = - 2

d ( common difference ) = - 2

To form A.P

a , a + d , a + 2d , a + 3d

- 2 , - 2 - 2 , - 2 - 4 , - 2 - 6

- 2 , - 4 , - 6 , - 8......

Answer 2

First terms of an A.P whose first term is -2nd common difference is -2

a1= – 2,

a2= a1 + d = – 2 + (– 2) = – 4

a3 = a2 + d = – 4 + (– 2) = – 6

a4= a3 + d = – 6 + (– 2) = – 8

First four terms are – 2, – 4, – 6, – 8
