Question

Find, first term, common difference, nth term of an A.P (√2,√8,√18,√32....)

Answer 1

Step-by-step explanation:

V2,2V2,3V2,4V2,.... a=V2 d=2V2-V2=V2 tn=a+(n-1)d tn=V2+(n-1)V2 tn=V2n

Answer 2

First term is root2
Common difference is root8-root2
=2root2-root2
=root2(2-1)
=root2
Nth term is first term+(n-1)difference
=root2+(n-1)root2
=nroot2 is nth term
