There are many possible answers. One possible rule is:
Un = (3n4 - 18n3 + 69n2 - 54n + 120)/8 for n 1, 2, 3, ...
It is: 3 6 12 24 48 .... double up each time
Because of the pattern of plus 11 then minus ten I would go with 13 24 14
The geometric mean of 15 and 24 is 18.973665961
The numbers fit the quintic function: t(n) = (27n5 - 556n4 + 4253n3 - 14876n2 + 23440n - 11784)/24 for n = 1, 2, 3, etc
15 out 24 in simplest form is 5 out of 8 because when you divide 15 by 3 you have to divide 24 by 3 to. so its 5 out of 8
You see the differences between the integers is 10,9,8.... so your difference for the next integer is 7
240/150 is one such.240/150 is one such.240/150 is one such.240/150 is one such.
multiply by 2 then subtract 6
Each number is decreasing by 3. The next numbers in the sequence would be -18, -21, -24, -27, -30.
150% of 24= 150% * 24= 1.5 * 24= 36
-150/240, -15000/24000
you add 10 to each number in the series of three. If you break the pattern into groups of three you will see 8-14-5 then 18-24-15 then 28-34. . . so 8+10=18+10=28, 14+10=24+10=34, 5+10=15+10=25, so continuing the pattern would be starting at 28: 28-34-25-38-44-35-48-54-45. . .
6, 15, 24, 33, 42, 51, 60
What percent of 24 is 150, written as an equation: P * 24 = 150Solve for P = 150/24 = 6.25 which is 625%
You can use equations to solve this: x multiplied by 24 = 3.6 24 24 (Divide by 24) x .15 Divide by 100 Your answer is 15% Hope I helped (I might have misunderstood your question we just learned this in Pre-Algebra so I'm not 100% sure)
There are infinitely many possible rules. One such is: Un = (-45n6 + 993n5 - 8385n4 + 33895n3 - 66930n2 + 59192n - 15360)/240 for n = 1, 2, 3, ...
150/240 is one equivalent fraction. 1500/2400 is another.
