According to patterns, what is the missing number in the sequence 1, 1, 2, 3, __?

The sequence presented is a classic example of the Fibonacci sequence, where each number is the sum of the two preceding numbers. Starting with the first two numbers:

• The first two numbers are both 1.

• The next number is calculated as 1 + 1, which equals 2.

• Following that, the next number is 1 + 2, resulting in 3.

To find the missing number after 3, we add the last two numbers in the sequence: 2 + 3. This gives us 5. Thus, the missing number in the sequence is 5, making it a natural continuation of the established pattern.

Since the Fibonacci sequence is well-recognized, identifying the next term requires applying the same addition logic used in the previous steps. Therefore, the correct answer aligns perfectly with the principles governing this mathematical pattern.
