B) 102
C) 101
D) 100
Correct Answer: C
Solution :
Given series is \[S=\frac{{{8}^{2}}}{{{5}^{2}}}+\frac{{{12}^{2}}}{{{5}^{2}}}+\frac{{{16}^{2}}}{{{5}^{2}}}+...10\]terms \[=\frac{{{4}^{2}}}{{{5}^{2}}}({{2}^{2}}+{{3}^{2}}+{{4}^{2}}+....10\,\text{terms})\] \[=\frac{16}{25}\left( \frac{11.12.23}{6}-1 \right)=\frac{16}{25}\times 505\] \[\therefore \]\[m=101\]You need to login to perform this action.
