Answer 1

Answer: let the terms of AP be a1, a2....an

-according to the question

a6=5*a1

a+5d=5a1.....1

and

a11=a5+3

a+10d=a+4d+3.................2

you can solve equation 1 and 2 using elimination method and get the value of a and d(common difference)

now substitute the value of a and d in:

a+7d

you will find the value of eighth term
