Arrange the numbers in ascending order, and then take the mean of the fourth and fifth number.
Well, darling, the first prime number is 2 and the fifth prime number is 11. Multiply those bad boys together and you get 22. So, the product of the first prime number and the fifth prime number is 22. Math doesn't have to be boring, honey!
The counting numbers (1, 2 ,3, . . . ) are called cardinal numbers.
fifth is an ordinal number!!!!
40 and 52

A = first U = second A = third I = fourth A = fifth

To find the fifth number, you can use the formula for finding the average of a set of numbers. The sum of the 5 numbers is 82 * 5 = 410. The sum of the 4 known numbers is 80 * 4 = 320. Therefore, the fifth number can be found by subtracting the sum of the 4 known numbers from the sum of all 5 numbers: 410 - 320 = 90. So, the fifth number is 90.
The sum of four numbers equals 40: a+b+c+d=40 Those same four numbers, along with another number (e), give the set a mean of 12: (a+b+c+d+e)/5=12 Use these two facts to determine e as follows: (a+b+c+d+e)/5=12 a+b+c+d+e=60 (a+b+c+d)+e=60 40+e=60 e=20
