To find the missing figure in the given sequence, let's analyze the pattern:
The given sequence is: 3, 5, 8, 13, 21, ...
To find the next number in the sequence, we can look for a pattern or relationship between the given numbers.
If we observe the differences between consecutive numbers, we get the following sequence:
2, 3, 5, 8, ...
The differences between consecutive numbers are increasing by 1 each time. This suggests that we are dealing with a quadratic sequence.
To find the next difference, we add 1 to the previous difference:
8 + 1 = 9
Now, let's find the next number in the original sequence by adding the next difference to the last number in the sequence:
21 + 9 = 30
Therefore, the missing figure in the sequence is 30.
Among the given options, the correct answer is A) 34, which is not among the given options. Hence, the correct answer is not among the given options.
