Question

. The first three terms of an A.P where first term is 3a+b and
Common difference is a-b, are​

Answer 1

Answer:

3a+b,4b and 5a-b are first three terms

Answer 2

Answer:

First term , a = 3a+b

Common difference , d = a-b

So ,  Next terms of AP be a+d , a+2d , ....

2nd term = a+d = 3a+b+a-b

=> 4a

3rd term = a+2d = 3a+b+2a-2b

=>5a-b

So the  First three terms are 3a+b , 4a , 5a-b
