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.
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.
91 is the dialling code for India. So you would add plus 91 (normally not plus plus 91) to dial a mobile with an Indian number. The phone need not be in India.
It's not possible to write down all the multiples of 91. If you brought me a number and told me that your number is the largest multiple of 91, then no matter how large your number was, all I would have to do would be to add 91 to it, and I would have another multiple of 91 that's larger than your number. There are an infinite number of them.

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.

There are three terms. You add the terms and divide by the numbers of terms to find the average/mean. Hence (91 + 93 + 95 ) / 3 279/ 3 = 93 the mean!!!!!
