The sequence alternates between two patterns: one decreasing by 3 and the other increasing by 1. Following this pattern, the next number after 14 would be 11 (14 - 3). Then, the number after that would be 15 (11 + 1). Thus, the next two numbers are 11 and 15.
The next figure would be 21, followed by 11 & 10.
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.
