To find the next number in the series 12, 5, 11, 21, we can look at the pattern of differences between the numbers. The differences are: -7 (12 to 5), +6 (5 to 11), and +10 (11 to 21). Continuing this pattern, we can assume the next difference will be +6 (to alternate between decreasing and increasing). Therefore, the next number would be 21 + 6 = 27.
32 The rule is to add 3n, where n is the number of the number in the series. (add 3, 6, 9, 12).
How about 3 followed by 12
The next whole number is 12.
What would be the next number in this series 15 12 13 10 11 8?
