4 15 59 235 939 3755 15019 etcThe numbers increase by multiplying by 4, then subtracting 1 from the answer.This can be seen by visual comparison of the first three numbers. That the fourth number follows this sequence can be checked by using a calculator.So what is the next number?And, if you are really clever, what number comes before the 4?
The next number in the sequence 3-15-6-30-21 is -207.
5
The next number in the sequence would be 25.
10 The sequence is given by xn = 60/n
235, the equation for this is n x 4 + 1

hmm 4*4 -1 =15 4*15 -1 = 59 4*59 -1 =235 4*235 -1 = 939
The next number in the sequence 3-15-6-30-21 is -207.
The next number could be 26 The next number could be 12 - - - - - - - - - The next number that is in the sequence is 12.
.75
The next number in the sequence is 48.
5
14

The next number after 15 will be 3. You are sequentially adding 9, adding 1, and dividing by 5.
The next number in the sequence would be 25.
