(1) The first term of an A.P is 6 and the common difference is 5. Find the A.P and its general term

Solution :

First term = 6

Common difference = 5

a  = 6

d  = 5

General form of A.P is a , a + d , a + 2 d , …………….

 6 , (6 + 5) , (6 + 2(5)) , …………..

 6 , 11 , (6 + 10) ,……………….       

Hence the required arithmetic progression is  6, 11, 16 , …………..
