The correct answer of problem C should be
AnsC
99
But I don’t know why my submission wasn’t being accepted.
(I’ve checked using Wolframalpha.)
the answer will be 100 you will be putting raw form of it which is N+1
no,
n+1=100
and, n=99
My approach was,
the sum of first n terms is,
\frac{(n+1)^2-1}{(n+1)^2}
You can prove it using induction
\frac{(n+1)^2-1}{(n+1)^2}=\frac{9999}{10000}
\Rightarrow\frac{(n+1)^2-1}{(n+1)^2}=\frac{100^2-1}{100^2}
i also have given the answer as 99 but my answer was rejected… it can also be done analysing the summation pattern
