Solution :
It is given that,
= 3 + 4n_____(1)
Now,
put n = 1, 2, 3 turn wise. So that we can find ,
and
.
★For finding ,
put n = 1 in (1)
= 3 + 4 (1)
= 3 + 4
= 7
★For finding ,
put n = 2 in (1).
= 3 + 4 (2)
= 3 + 8
= 11
★For finding ,
put n = 3 in (1).
= 3 + 4 (3)
= 3 + 12
= 15
So, the AP will be :
7, 11, 15 .........
