What is the rule to the pattern 0 2 6 12?

It looks like it could be: 0 + 2 = 2 2 + 4 = 6 6 + 6 = 12 The next logical answers would be: 12 + 8 = 20 20 + 10 = 30 30 + 12 = 42 And so on...


Is the pattern 3 6 12 24 48 96 recursive?

Yes, the pattern 3, 6, 12, 24, 48, 96 is recursive. Each term can be derived from the previous term by multiplying it by 2. For example, 3 × 2 = 6, 6 × 2 = 12, and so on. This consistent multiplication by 2 defines the recursive relationship in the sequence.

What the next number in pattern 2-6-3-8-6-12?

To identify the pattern, we can look at the differences between the numbers: the first difference is +4 (2 to 6), the second is -3 (6 to 3), the third is +5 (3 to 8), the fourth is -2 (8 to 6), and the fifth is +6 (6 to 12). The pattern appears to alternate between adding an increasing number (4, 5, 6) and then subtracting a smaller number (3, 2). Following this pattern, the next operation would be to subtract 1 from 12, resulting in 11. Thus, the next number is 11.

What number is missing 3 6 12 6 12 24 18?

The missing number in the sequence is 36. The pattern alternates between multiplying the previous number by 2 and then adding 6, as seen in the progression: 3 (×2) = 6, 6 (×2) = 12, 12 (×2) = 24, and 24 (×1.5) = 36. Following that, 18 (×2) would be the next logical number after 36.


What pattern is this 3 6 10 12 12 10 6 3 1?

The full series should be: {1, 3, 6, 10, 12, 12, 10, 6, 3, 1} It is nothing more than a series that increases in a certain way & then decreases in the exact opposite way. You can see this by using subtraction as follows: 3-1 = 2 6-3 = 3 10-6 = 4 12-10 = 2 12-12 = 0 12-10 = 2 10-6 = 4 6-3 = 3 3-1 = 2 Notes: - the series pattern increases to 12 in this way: 2, 3, 4, 2 - the series pattern then decreases from 12 in the exact opposite way: 2, 4, 3, 2 - if graphed with time as the x-coordinate & each number as the y-coordinates, the full series would resemble a curve that looks similar to a hill with a flat top.
