What is the next number in the Fibonacci sequence after 3, 5?

The Fibonacci sequence is a series of numbers in which each number is the sum of the two preceding ones, typically starting with 0 and 1. In this specific scenario, the sequence is given as 3 and 5. By applying the Fibonacci rule, to find the next number, you would add the two numbers together:

3 + 5 equals 8.

Thus, after 3 and 5, the next number in the Fibonacci sequence is 8. This aligns perfectly with the standard definition of the Fibonacci sequence, where numbers are generated by this additive process. It maintains the essence of the pattern, confirming that the correct answer is 8.
