I think this question is incorrect as 65 and 69 won't come in the series 3, 7,11,15.......
Thought we assumed that term 1/65 will be cancelled out by a term -1/65 which is not going to happen here??

$(\frac{1}{3.7} + \frac{1}{7.11} + \frac{1}{11.15} + \frac{1}{15.19} + \dots + \frac{1}{65.69})$ is equal to

Options:

$\frac{6}{49}$

$\frac{25}{138}$
