The Fibonacci sequence begins 0, 1, 1, 2, 3, 5. What is the next number?

The next number in the Fibonacci sequence can be determined by understanding the pattern in the series. The Fibonacci sequence is constructed by adding the two preceding numbers to obtain the next number.

In this case, the last two numbers in the provided sequence are 3 and 5. If you add these two numbers together:

3 + 5 = 8

Thus, the next number in the sequence following 0, 1, 1, 2, 3, and 5 is indeed 8. This shows how the Fibonacci sequence grows as you continually add the two previous numbers together. The reasoning behind the other choices can be considered, but they do not follow the established pattern found in the Fibonacci series.
