4 6 9 13 18 24 31 39 ......
Add 2 to 4 to get 6 then add 3 to 6 to get 9 then add 4 to 9 to get 13 and so on.
Arrange in order: 12 13 13 14 16 18 19 The median is the number in the middle, where there are are as many other numbers on one side as the other: Answer is median = 14
Think of the prime numbers that add up to 18. 5 and 13 7 and 11 2, 5 and 11 2, 3 and 13 Nine 2's Multiply them. The first two are 65 and 77.
To find the median in a group of numbers, you need to arrange the numbers from least to greatest, and find the one in the middle. (It's pretty simple if you have an odd number of values, but if you have an even number of values, you can add the two in the center and divide them by 2.The numbers you listed, when put in order from least to greatest, are:11 13 15 18 20 20 22If you look at it for a second, you'll see that the number in the center is 18. So, the median is 18.

The mode is the number which occurs most - so this is 20 The median is the middle number if you write them all in numerical order..... 5, 13, 13, 15, 18, 20, 20, 20 The answer is 16.5 which is in the middle of 15 and 18 To find the mean you add all the numbers up 5+13+13+15+18+20+20+20=124 then divide by the number of numbers in the range (8). 124/8 = 15.5
13 and 5 13+5=18 13x5=65
The range of these numbers, the difference between the highest and lowest of these numbers, is equal to 28-15 = 13.
Prime numbers are: 2, 5, 13, & 178, 18, 93, 117 are composite numbers.
Arrange in order: 12 13 13 14 16 18 19 The median is the number in the middle, where there are are as many other numbers on one side as the other: Answer is median = 14
4, 14, 18 and 10 are composite numbers.
The least common multiple of the numbers 18, 13 and 37 is 8,658.
The two numbers are 13 and 18
There are two pairs of prime numbers that express 18 as the sum of two prime numbers: 7 + 11 = 18 and 5 + 13 = 18.
Think of the prime numbers that add up to 18. 5 and 13 7 and 11 2, 5 and 11 2, 3 and 13 Nine 2's Multiply them. The first two are 65 and 77.
2, 3, and 13 are all prime numbers and their sum is equal to 18.
