Question

The 10th term of sequence √2, √8, √18.....is?​

Answer 1

Root of 200 or 10Xroot 2

Answer 2

Answer:

AP:

$\sqrt{2} , 2\sqrt{2} , 3\sqrt{2}.........................$

let a & d be the first term and the common difference respectively

a $= \sqrt{2}$

d $= 2\sqrt{2} - \sqrt{2}$ $= \sqrt{2}$

n = 10

$t_{10} = a + (n - 1)d$

$t_{10} = \sqrt{2} + (10 - 1)\sqrt{2}$

$t_{10} = \sqrt{2} + 9\sqrt{2}$

$t_{10} = 10\sqrt{2}$

$t_{10} = 200$
