Question

\[If Sn = 1/\left( 1+\sqrt{n} \right) +1/\left( 2+\sqrt{2n} \right) +1/\left( 3+\sqrt{3n} \right)+.......1+\left( n+\sqrt{n ^{2}} \right)\]
Then Sn is
a. log2
b. log 4
c. log 8
d. 1/2 log2
Give correct answer by solving.

Answer 1

Do you mean the limit of Sn?

Answer 2

It is the question from binomial theorem.

Answer 3

Sn depends on n and none of your choices depends on n

Answer 4

Here,Sn represents the logarithmic series.
