They are: 7 times 13 = 91
7 x 13 = 91
1 x 91, 7 x 13
91 = 7 x 13
The two numbers that add to 20 and multiply to 63 are 7 and 9. When you add them together, 7 + 9 = 16, which does not meet the requirement. However, to find the correct numbers, we can set up the equations: ( x + y = 20 ) and ( xy = 63 ). Solving these, we find that the numbers are 7 and 13, since 7 + 13 = 20 and 7 * 13 = 91, which does not meet the requirement. The correct pairs are 15 and 5, which add to 20 and multiply to 75.
The numbers are 89, 91 and 93 and 90, 91 and 92
Two consecutive numbers which add up to 91 are the numbers one half either-side of 91/2 = 45.5. Therefore, the numbers are 45 + 46 = 91.

The numbers are 88, 89, 90, and 91.
To get a mean of 91 from two numbers the two numbers should add up to 182 (2x91), so if one number is 71.2, then the other number is 182-71.2=110.8.
