1. 47 is prime.
Many combinations of number have a mean of 24. For example, 22, 23, 24, 25, and 26 have a mean of 24. To find a mean, add the numbers and divide by the count of the numbers (the number of observations): (22 + 23 + 24 + 25 + 26) ÷ 5 = 24 ...but so does this: (20 + 22 + 24 + 26 + 28) ÷ 5 = 24 ...and this: (-96 + -4 + 30 + 72 + 118) ÷ 5 = 24 ...and so on...

21, 22, 23, 24, 25, 26, and 27
Ans: 25 26 Reasoning: read every second number. From first number: 30 29 28 27 26 __(pattern of -1). From second number: 21 22 23 24 25 __(pattern of +1)
What I did was divide 150 by 6 (because of the six integers) 150/6 = 25 I then just subtracted one and added one to get the first two even integers 25 - 1 = 24 25 + 1 =26 Then added two to the high one and subtracted two from the low one 24 - 2 = 22 26 + 2 = 28 Repeat above step 22 - 2 = 20 28 + 2 = 30 20 + 22 + 24 + 26 + 28 + 30 = 150

Here you go: 22 - XXII 23 - XXIII 24 - XXIV 25 - XXV 26 - XXVI
27 and 1/3
..... 27, 24, 26, 25, 25, 26, 24, 27, 23 .....A number is decreasing by 1 while another number is increasing by 1
The composite numbers between 20 and 30 are: 20 21 22 24 25 26 27 28 30
