For {12, 15, 18} each term is the previous term plus 3; a general formula for the nth term is given by t(n) = 3n + 9.
For {12, 24, 36} each term is the previous term plus 12; a general formula for the nth term is given by t(n) = 12n.
10/12 15/18 20/24 ect...10/12, 15/18, 20/24
5/6, 10/12, 15/18, 20/24

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.
The first three multiples of 12 are 12, 24, and 36.
The median is 13.5
6, 12, 18, 24 15, 30, 45, 60
They are: 3 6 9 12 15 18 21 and 24 itself makes 8 of them
The LCM is 2520.
3, 6, 9, 12, 15, 18, 21, 24, 27, 30, 33, 36, 39 . . .
(21+15+19+28+10+17+9+15+26+14+10+18+24+12+16) / 15 = 16.93 recurring (that is, 16.93333...)
The rule for the sequence 6, 18, 24, 30 is that each number is obtained by adding 12 to the previous number. This is because 6 + 12 = 18, 18 + 6 = 24, and 24 + 6 = 30. Therefore, the pattern is increasing by 12 each time.
