Question

please help in getting the common difference of root 2 + root 8 +root 18 +root 32 in A.P(Arithmetic Progression)

Answer 1

√2 +√8+√18+√32 is the given

so common difference is

$a_{2} - a_{1}$ =d

let √2 be√2 itself ......$a_{1}$

√8 = 2√2.......$a_{2}$

√18=3√2

√32 = 4√2

so d = 2√2 -√2

d = √2
