Answer 1

Answer:

The correct option is A

The missing number is 34

Step-by-step explanation:

By inspection, the third number is obtained by adding the two preceding numbers.

1 + 1 = 2

The next number is obtained by adding the two preceding numbers.

2 + 1 = 3

This continues as:

3 + 2 = 5

8 + 5 = 13

13 + 8 = 21

21 + 13 = 34
