Step-by-step explanation:
Let's add the terms and see if there's a pattern

Suppose we say the sum of n terms is (n/(2n+1)), the next term in the series will be 1/((2n+1)(2n+3)) and adding that to the presumed sum gives ...

Then it appears the sum of n terms is (n/(2n+1)). So, the sum of 24 terms is ...

So I think that number 6 is just dividing by 3 and the second one doesn't like divide so number 7 is no and number 6 is yes
