18+12+20+24=74
74/4=18.5
The average of 18, 24, and 18 is (18 + 24 + 18) / 3 = 20.
The average is 18.
10/12 15/18 20/24 ect...10/12, 15/18, 20/24
12 + 24 * 6/18 = 12 + 24 *1/3 = 12 + 8 = 20
18
A. 12 and 18
20
12 11 18 14 24 17 30 20.. i think ;-) pattern: 18-12 = 6 14-11 = 3 24-18 = 6 17-14 = 3 i hope that helps.
He scored 12 points in his sixth game to average 20 points in the six games.23 + 18 + 16 + 24 + 27 + 12 = 120120/6 = 20
5/6, 10/12, 15/18, 20/24
12, 18, 20, 24, 30
In order, the numbers are 18, 21, 24 and 37. Since there are an even number (4) of them, the median is the average of the middle two. ie median = (21+24)/2 = 22.5
