Answer:

The answer to this question is 845.761

Step-by-step explanation:

given that, the first term is 2/7

So, using the given formula we get, the second term as (1-2/7)/(1+2/7) = 5/9

, the third term as (1-5/9)/(1+5/9) = 2/7 and the fourth term as 5/9 and so on

( The 2011th term will be 2/7 since the value of each odd term is 2/7)

Therefore,the sum of first 2011 terms is (1005(5/9) + 1006(2/7)) = 845.761
