Question

What is the first term and common difference of √2, √8, √18, √32

Answer 1

HEYYA USER !!

HOPE MY ANSWER WILL HELP YOU IN ANYWAY :)

√2= (a1),

√8= (a2),

√18= (a3),

√32= (a4)

1st is represented by "a1"

so for this series our, a1 = √2

and conman difference i.e, "d" isn't same

like ,

if , d = a2 - a1 = √8 - √2 }-----(1)

d = a4 - a3 = √32 - √18}-----(2)

hence , for "d" we have different values in equation (1) and (2)

∴ (1) ≠ (2)

∵we can't consider it as an AP !!

HOPE U R CLEAR ^_^
