2+3=53+5=85+8=1313+21=3333 is the next number in this pattern. This pattern is called a Fibonacci.
The next number will be 13+21 = 34
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.
