Given : An Arithmetic progression whose first term is 20 and
common difference is 8
To Find : AP
Solution:
AP - Arithmetic progression is of form
a , a + d , a + 2d , a + 3d ,
a = first term
d = common difference
a = 20
d = 8
a = 20
a + d = 20 + 8= 28
a + 2d = 20 + 2(8) = 36
a + 3d =20 + 3(8) = 44
and so on
nth term = a + (n - 1)d = 20 + (n - 1) 8
= 8n + 12
AP
20 , 28 , 36 , 44 , 52 and so on
