1. The problem statement, all variables and given/known data Find n so that: 1/(1+√3) + 1/(√3+√5) + 1/(√5+√7) + .... + 1/(√2n-1 + √2n+1) = 100 Find n so that the same sum equals any number x (instead of 100) 2. Relevant equations sum (1/(√2n-1 + √2n+1) = 100 3. The attempt at a solution i have proven using the first 3 given terms that this series cannot be geometric or arithmatic. But if its neither how does my teacher expect me to find when the series equals 100? what do i do? where do i go from here?
