The answer is 35.
The next number after 15 will be 3. You are sequentially adding 9, adding 1, and dividing by 5.
25
take the first three numbers and the remaining three numbers, they both have the same patern: 15+9=24 24+1=25 and 5+9=14 14+1=15now what relates both groups is the division of the last number of the 1st group by 5 to get the first number of the remaining three which is also 5 (check it)now repeating the same thing for 15 (the last of the second three) you will get 3 then 3+9=12 then 12+1=13
You could go for add 9, add 1 divide by 5 or you could have the polynomial (-30x5 + 513x4 - 3232x3 + 9171x2 - 11438x + 5376)/24 and according to that, the next number is -266
-5.The patterns seems to be "+9 +1 -20" repeat.And, 15 - 20 = -5.
The answer is 35.
-5
Add numbers then divide total by amount of numbers So 14 16 has mid number of 15 as (14+16)/2 = 30/2 = 15 (as there are 2 numbers of 14 and 16) or 6 12 24 has mid number of 14 as (6+12+24)/3 = 42/3 = 14 (as there are 3 numbers of 6 and 12 and 24) and so on
Least Common Multiple (LCM) for 15 14 24 is 840.
The Least Common Multiple (LCM) of 14, 15, and 24 is 840.
25 every third number add 10 14 / 24 / 34 5 / 15 / 25 18 / 28 / (38) 14 5 18 24 15 28 34 25 38 44 35 48 54 45 58 64 55 68 74 and so on ...
The next number after 15 will be 3. You are sequentially adding 9, adding 1, and dividing by 5.
5/8 + 7/12 = 15/24 + 14/24 = 29/24 = 1 and 5/24.

This series follows the following repetitive pattern:Subtract 4divide by 3multiply by 2Give this context, the next number would be 12.
