Given an example of a number which is divisible by 2 but not by 4,              (ii)   3 but not by 6. 4 but not by 8,              (iv)   both 4 and 8 but not by 32.

Explanation

(i) `2` but not by `4`.
Any number which follows the formula of `4n + 2` is an example of a number divisible by `2` but not by `4`.
i.e., `10` where `n = 1`.

(ii) `3` but not by `6`.
Any number which follows the formula of `6n + 3` is an example of a number divisible by `3` but not by `6`.
i.e., `15` where `n = 1`.

(iii) `4` but not by `8`.
Any number which follows the formula of `8n + 4` is an example of a number divisible by `4` but not by `8`.
i.e., `28` where `n = 1`.

(iv) Both `4` and `8` but not by `32`
Any number which follows the formula of `32n + 8` or `32n+16` or `32n +24` is an example of a number divisible by both `4` and `8` but not by `32`.
i.e., `48` where `n =1`.
