Fill in the number that fits best: 1, 2, 4, 7, 11, …, 22.

The problem is based on the pattern of numbers.

Answer: The number that fits best in the sequence 1, 2, 4, 7, 11, …, 22 is 16.

Let's find the missing number in the sequence: 1, 2, 4, 7, 11, …, 22

Explanation:

Les take the difference of these numbers:

1, 2, 4, 7, 11, ..., 22

So, the rule boils down to:

1 + 0 , 1 + 1, 2 + 2, 4 + 3, 7 + 4 , 11 + 5, 16 + 6,  22 + 7, ...

Thus, 16 is the number that fits the best in 1, 2, 4, 7, 11, …, 22.
