hello friends,
it allegedly a very simple question, most of the people answered the answer is 9=90. i claim that theoretically, we can't be 100% sure about the right answered because we don't know how the function // series behaves at higher numbers, but most other people claim that this is a definite series in which you can know the matching numbers up to infinity.
i Hope you are able to understand exactly what i meant. So....&&& .who's right?
