You can, of course, make up infinitely many sets that contain this number. Some important sets that include it are:
S:{6,8,10,12,14} read as: The set S contains all even numbers between 5 and 15.
The LCF of any set of numbers is 1.
15 because its an odd number whereas 6, 10 & 12 are even numbers.
12
The answer is 12 every other numbers are odd numbers, but 12 is an even number
There are infinitely many such numbers. they belong to the set n*15 where n is any integer.
To any set that contains it! It belongs to {-15}, or {sqrt(2), -15, pi, -3/7}, or all whole numbers between -43 and 53, or multiples of 5, or composite numbers, or integers, or rational numbers, or real numbers, or complex numbers, etc.
Its a NEGATIVE number. A NEGATIVE INTEGER.
The set {15}.
Whole numbers consist of numbers from 0 to infinity. 15 is included in this set which makes it a whole number. Side Note: 15 is also a counting #, integer, rational #, and a real #
Go look in a book
Real numbers, Rational numbers, and Integers.The other three are Irrational (numbers that cannot be expressed as fractions), Whole numbers (0,1,2,3,4...) and Natural numbers (1,2,3,4,5...).EDIT: There is also imaginary numbers (√-1, often expressed as i ) and complex numbers (numbers that contain both a real and imaginary part i.e. a+bi where a and b are real numbers and i is an imaginary number)
-15
19 doesn't belong. The rest of the numbers are multiples of 3.
15 and 30
The mean or average of THIS set of numbers is found by adding the 6 numbers and dividing by 6. 90/6 = 15.
Set of odds numbers divisible by 5 between 10 and 20?
