Question

(х) а, 2а, 3а, 4а, ....find d common difference and write three more terms​

Answer 1

Answer:

d(common difference)= 2a-a=a

3 more terms= 4a+a, 4a+2a, 4a+3a

= 5a, 6a , 7a

Answer 2

Ap.a, 2a, 3a, 4a.......

a=a, d=4a-3a=a

we know

first term=a

second term=a+d=a+a=2a

third term=a+2d=a+2(a) =3a

fourth term=a+3d=a+3(a) =4a

fifth term=a+4d=a+4(a) =5a

sixth term=a+5d=a+5(a) =6a

seventh term=a+6d=a+6(a) =7a
