The spacing is 6 1+6=7 7+6=13 13+6=19 19+6=25 so the missing number in the sequence is 13
It is: 1 and 13/40

The sequence 1-1-2-3-5-8-13 is known as the Fibonacci sequence. In this sequence, each number is the sum of the two preceding ones, starting from 1 and 1. Thus, the next numbers would be 21 (13 + 8) and 34 (21 + 13). This pattern continues indefinitely.
10 (between 7 and 13)
21
The next number in the sequence is 18. It's +1, +2, +3, +4, ....
The sequence 14567911 appears to be a series of increasing odd numbers: 1, 5, 7, 9, and then jumps to 11. Following this pattern, the next odd number after 11 is 13. Therefore, the next number in the sequence is 13.
Start with the numbers 1 and 1. After that, every number in the sequence is the sum of the previous two numbers. Thus, the sequence starts with: 1, 1, 2, 3, 5, 8, 13, ...
