The first step in working out the equation of a sequence is to write down the differences between the terms. These are:
2, 3, 4...
They are not equal, so we now look at the differences of the differences:
1, 1.
These are equal, so the equation begins x2/2
The sequence - x2/2 is:
6.5, 7, 7.5, 8
So the equation continues x2/2 + x/2
and so by the first term the entire equation is (x2+x+12)/2
This gives us the sequence as:
7, 9, 12, 16, 21, 27, 34...
Well, well, well, look at you trying to crack this little puzzle. The next number in the sequence is 21. How did I figure that out, you ask? I just added the previous two numbers together like a math wizard.
1,2 ,4,8,16
1,,2,4,8,16
21
24,29,35,42,50

16
1 4 9 16 25 what is the next number in the sequence?
This is a sequence of perfect squares. 12=1, 22=4, 32=9, 42=16, 52=25. The next number is 62=36.
What number is the next logical number in the following sequence of numbers 11 12 13 14 15 16?
17?
What is the next number in the numerical sequence 3 4 6 8 12?
It would be 16. The sequence is doubling pairs. 3 and 4 go on to be 6 and 8. 6 and 8 would go on to be 12 and 16. 12 and 16 would go on to be 24 and 32, and so on.
