Answer 1

Answer:

➡ AP :- 3, 5, 7, 9, ....

Step-by-step explanation:

Given,

3rd term = a+2d = 7 ....(1)

6th term = a+5d = 13 .....(2)

Subtracting (1) from (2) we get

a+5d=13

a+2d=7

- - -

$3d = 6$

$d = \frac{6}{3}$

d=2

Now, from (1)

a+2d=7

=> a=7-4

=> a= 3

Now,

a1=3

a2= a+d = 5

a3= a+2d = 7

a4 = a+3d = 9

Therefore,

AP is 3,5,7,9,.....
