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...

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.

Sequence 2 4 16 64?
The next number in the sequence 2, 4, 16, 64 is 256.
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.
What number is next in this sequence would complete this 2 -6 12 4 20?
To find the next number in the sequence 2, -6, 12, 4, 20, we can look for a pattern. The differences between consecutive numbers are -8, 18, -8, and 16, suggesting a pattern of alternating increases and decreases. Following this pattern, the next difference should be -8, so we subtract 8 from 20, giving us 12. Therefore, the next number in the sequence is 12.
