Finding the Pattern

To find the missing number in the sequence 1, 1, 2, 4, 7, 13, 24, ?, 81, 149, let's analyze the given numbers and try to identify a pattern.

Looking at the sequence, we can see that each number is obtained by adding a certain value to the previous number. Let's calculate the differences between consecutive numbers:

- The difference between the first and second numbers is 0. - The difference between the second and third numbers is 1. - The difference between the third and fourth numbers is 2. - The difference between the fourth and fifth numbers is 3. - The difference between the fifth and sixth numbers is 6. - The difference between the sixth and seventh numbers is 11. - The difference between the seventh and eighth numbers is 21. - The difference between the eighth and ninth numbers is unknown. - The difference between the ninth and tenth numbers is 68. -
