Question

the 16 term of an ap 3,7,9,11 i​

Answer 1

Answer: 63

Step-by-step explanation:

Here we need to find the 16th term so n becomes 16 a the first term of ap becomes 3 and the difference d is equal to 4.

a = 3 ; d = 7-3 = 4; n = 16

We know the formula to find the nth term which is

t_(nth) = a + (n-1)d

By substituting the values we get

t16 = 3 +(16-1)4

= 3 + (15 x 4)

=3 + 60

= 63
