5. If the mean ("average") of the first five numbers is 11, that means they add up to 55 (5 times their mean value of 11). Similarly, all six numbers have to add up to 60 (6 times their mean value of 10). The final number is the difference between these sums (60 - 55), or 5.
Assuming the first five numbers is meant to refer, not to the first five real numbers but to the first five positive integers, the answer is 1*2*3*4*5 = 120
10,000 is the smallest five-digit number because it is the first number that contains five digits. Numbers are categorized by the number of digits they have, and a five-digit number ranges from 10,000 to 99,999. Since 10,000 is the lowest value within this range, it is considered the smallest five-digit number.
Then it is 2310.
Two (assuming you are talking about real numbers). In general, for any given positive number, there will be two real numbers whose absolute value is that given number. In the case of complex numbers, the answer is "infinitely many" - all the numbers on a circle centered on the origin, with that radius, have that absolute value.
(2,1), (4,3), (6,5), (8,7) and (10,9).
Just multiply the first five prime numbers! 2x3x5x7x11 = 6x35x11 = 210x11 = 2310. Any multiple of this number "has the first five prime numbers as factors", but 2310 is the smallest such number.

The first five natural numbers are 1, 2, 3, 4, and 5. Natural numbers are the set of positive integers used for counting and ordering. They do not include zero or negative numbers.
The first prime numbers are 2, 3, 5, 7, 11. When multiplied together the product is 2310. It is the smallest number that has the first five numbers as its factors.
