Take note that we cannot consider the 1 for the last blank, since

it will be repeated for 1 * 1. We cannot include the number which are prime, like 2, 3, 5 and 7. Since it will be repeated as well.

FOr instance, if we consider 3. We will have:

3 * 1 = 2 + 1 = 3

We cannot consider numbers which is a perfect square, since we will have repeatition as well.

For instance, if we consider 4.

2 * 2 = 3 + 1 = 4.

We can try the remaining numbers: 6 and 8.

**2 * 3 = 5 + 1 = 6**

**2 * 4 = 5 + 3 = 8**

**There are no repetition, hence that is our answer.**
