Oh, dude, the mean is just the average of those numbers. So, you add them all up (96 + 49 + 68 + 75), then divide by how many numbers there are (which is 4 in this case). So, like, the mean would be 72. That's it, pretty simple stuff.
The two numbers you are looking for are 7 and -49. They add up to 42 (7 + (-49) = 42) and multiply to -343 (7 * -49 = -343).

The two numbers that add up to 53 and multiply to 196 are 49 and 4. This is because 49 + 4 = 53 and 49 × 4 = 196.

The two numbers that multiply together to get 1225 and add up to 74 are 25 and 49. You can verify this by calculating: 25 × 49 = 1225 and 25 + 49 = 74.
