Question

The sum of 1st and 9th term of an AP is 44. its 4th term is 18. What is its 6th term?​

Answer 1

Answer:

Here,

a4=a+3d

a8=a+7d

 

Therefore,

a+3d+a+7d=24

2a+10d=24

a+5d=12     …… (1)

 

Again,

a6=a+5d

a10=a+9d

 

Therefore,

a+5d+a+9d=44

2a+14d=44

a+7d=22    ……. (2)

 

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

d=5 and a=−13

 

Therefore,

a1=a=−13

a2=a+d=−13+5=−8

a3=a+2d=−13+10=−3
