The sum of the numbers 5, 16, and 22 is 43.
There are 5460 five digit numbers with a digit sum of 22.
17 + 5 = 22 17 - 5 = 12
To find the average of the numbers 16, 18, 20, 22, and 24, add them together: 16 + 18 + 20 + 22 + 24 = 100. Then, divide the sum by the number of values, which is 5. So, the average is 100 ÷ 5 = 20.
5 & 21
17 and 5
9801 * The sum of the first two odd numbers (1+3) is 4, or 22 * The sum of the first three odd numbers (1+3+5) is 9, or 32 * The sum of the first four odd numbers (1+3+5+7) is 16, or 42 * ...and so on So the sum of the first 99 odd numbers, using the pattern above, would be 992 or 9801.
3 + 13 = 16 5 + 11 = 16
