Subtract two, multiply by two, subtract one. :)
3, looks as if you add 9 to the first number, then add 1, divide by 5, add 9, add 1, divide by 5 to get 3
10 30 15 16 48 24 25 75...

The answer is 35.

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.

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
