I think you meant to write: 1+4+16+64+256 which would make the value of 'r' to be r=4. To get from 1 to 4, you multiply 1 by 4 to get 4. To go from 4 to 16, you multiply 4 by 4 to get 16. This pattern continues. To find the value of 'r', just pick any term and divide that term by the previous term. For instance, r=64%2F16=4
