They are: 7 times 13 = 91
7 x 13 = 91
91 = 7 x 13
1 x 91, 7 x 13
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.
631
The numbers are 88, 89, 90, and 91.
91
Two is the only even prime number. When you add an odd number to another odd number, you get an even number. When you add an even number to an odd number, you get an odd number. 91 is an odd number, therefore the answer is 2 and 89.
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.
91+31+151=273
