'from 100' ??? If you mean 'less than 100' then there are 25 primes. If you mean 'more than 100' then the answer is infinite, just like numbers are infinite.
100 times the mean, or 4783, because the mean is defined as the sum of all the numbers divided by the number of the numbers.
Depending on how you look at it, there are either 99 or 100 whole numbers up to 100. If you mean up to and including 100, then the answer is 100 whole numbers, if not, then the answer is 99 whole numbers.
That depends what the numbers are.
The geometric mean of 25 and 100 is the square root of 2500 which is 50. In general, the geometric mean of n numbers is the n-th root of the product of the numbers.
You divide by the number of numbers - if you want the mean of three numbers you divide by 3, if you want the mean of a hundred numbers you divide by 100.
Any odd number of consecutive numbers in which the center number is 100 will have this property. The simplest example is 99, 100, 101.
I am not at all sure about "present". If you mean percent, the answer depends on which 100 numbers. Between 900 and 999, for example, the answer is 0%. For the FIRST 100 numbers: 1 to 100, the answer is 6%.
It is: 10+25+30+35 = 100 and 100/4 = 25 which is the average mean value
The average is all the numbers added together and divided by how many numbers there are. In this case: 78+100=178. 178/2=89. Therefore the mean/average of the two numbers is 89.

(1, 5, 97, 99, 100, 100) The mode is 100. The median is 98. The mean is 67.
