Question

find the nth term of an A.P whose first term is 20 and command difference is 4​

Answer 1

a = 20

d = 4

nth term = a + (n-1)d

= 20 + 4n - 4

= 4n + 16

Answer 2

Answer:

nth Term of the AP is 24 + 4n

Step-by-step explanation:

Given first term, a = 20

common difference, d = 4

nth term of an AP is given by

An = a + ( n–1 ) d

= 20 + ( n – 1 ) 4

= 20 + 4n – 4

= 24 + 4n

or = 4 ( 6 + n)
