To find the next number in the sequence 5, 15, 12, 24, 21, 21, 18, we can analyze the pattern. The differences between the numbers are: 10, -3, 12, -3, 0, -3. Following this pattern, the next difference would likely be 12, resulting in a next number of 18 + 12 = 30. Thus, the next number in the sequence is 30.
18 plus 4, minus 2
The pattern is X*2=Y-2+Z: 4*2=8 8-2=6 6*2=12 12-2=10 etc.
The Least Common Multiple (LCM) of 18, 10, and 12 is 180.
add 6, subtract 2
what is the mode of the following data 18, 17, 12, 14, 8, 21, 10, 11, 19, 20, 10, 5, 17, 12, 10, 20
8+10=18 18*10=180180+11=191191*11=21012101+12=21132113*12=25356
18 plus 4, minus 2
First, to find median put numbers in order so: 5, 5, 6, 7, 8, 9, 10, ( 10, 12 ,) 14, 15, 17, 18, 18, 18, 20 10 + 12= 22 divided by 2= 11, the median is 11
The pattern is X*2=Y-2+Z: 4*2=8 8-2=6 6*2=12 12-2=10 etc.
The Least Common Multiple (LCM) of 18, 10, and 12 is 180.

Here's some: 10/12 15/18 Notice a pattern?
20 + 10 - 12 = 18
4+4=12 12+6=18 18+6=24 24+10=34 34+10=44
The series 1318162119 appears to be a sequence where each number is formed by concatenating the first few even numbers. The pattern is: 2 (2), 4 (4), 6 (6), 8 (8), 10 (10), 12 (12), 14 (14), and 16 (16). Following this pattern, the next even number is 18, which would be represented as "18" in the series. Thus, the next number in the series is 20, resulting in the next sequence being 131816211920.
It is: 12+(-4)-(-10) = 18
