Question

in an ap 1st term is 11 and 3rd term is 27. find 4th term?​

Answer 1

Answer:

a=11,a+2d=27,2d=16,d=8,a+3d=35

Answer 2

Step-by-step explanation:

Given :- a1 = 11

a3 = 27

a1 + 2d = 27

11 + 2d = 27.

2d = 27 - 11

2d = 16

d = 16 ÷2

d= 8.

Therefore, a4 = a1 + 3d

= 11 + 3 × 8.

= 11+ 24

a4 = 35
