{'numbers': [0, 1, 0, 0], 'sequence': [0, 1, 0, 2], 'value': [0, 0, 1, 0]}

To find the value of `X` in the given sequence of numbers, let`s analyze the pattern:

The given sequence is obtained by starting with 5 and adding the previous two numbers to get the next number.

5 + 8 = 13

8 + 13 = 21

13 + 21 = 34

21 + 34 = 55

34 + 55 = 89

So, the missing number `X` is obtained by adding 8 and 13:

Therefore, the value of `X` is 21.
