First, let's find the sum of 100 terms, where a1 is 1 and an = 100.

Sn = (n/2)(a1 + an)

S100 = (100/2)(1 + 100) = 50(101) = 5,050

The average of all whole numbers from 1 to 100 is: 5,050/100 = 50.5

Are all numbers from 100 to 1000 are whole numbers?

No, they're not. The range from 100 to 1,000 includes numbers like 100.6, 239.07,5431/2, and 942.638, and those are not 'whole numbers'.But the numbers in that range that have nothing after the decimal point, and haveno fraction after them, are all whole numbers.The same is also true of any number that's notbetween 100 and 1,000 .


Can the answers of factorials be decimals?

No. Factorials can only be placed on positive whole numbers or 0. For example, 0!, 1!, and 6! are all fine, but 2.5! and (-1)! are not. Since factorials can only be placed on whole numbers, that means you will only be multiplying whole numbers. 100! = 100 * 99 * 98 ... * 1; all those numbers are whole numbers, meaning your answer will be a whole number.
