Question

□,8,□,2 find missing number of AP

Answer 1

Answer:

11 and 5

Step-by-step explanation:

In an AP, the first term is a and the third term is a+2d.

Given, second term = 8

So, a+d=8 ------ (1)

Also, fourth term = 2

So, a+3d=2 -------(2)

Solving equations (1) and (2), we get

8-d=2-3d ==> d=-3

Put d=-3 in (1)

a-3=8 ==> a=11

Hence, the first term is a=11

and the third term is a+2d=11+(-6)=5
