Hey there!
√2 - √2 +√2 - ......... ( infinity)
There are two possible solutions for this :
1) 0
2) √2 .
If the last term is -√2 , All the pairs would cancel out ,giving 0 .
If the last term is √2 , Then all pairs would cancel out, leaving √2 , Hence √2 would be answer .
There is no exact answer, But You can take the range of answer to be 0 to √2
