The next number in the sequence 5-7-13-31 is 69.
1, 1, 2, 3, 5, 8, 13, 21, ...Restate the question: What are the terms of the Fibonacci sequence?The Fibonacci sequence is formed by beginning with the first two terms both equal to one. From there on, each term is found by adding the two previous terms:1+1=2, 1+2=3, 2+3=5, 3+5=8, 5+8=13, 8+13=21, ...
The nest number in the sequence is 18. Note that the difference between each number and the next number in the sequence follows the simple sequence of 1,2,3,4. Obviously the next in the sequence of increases is 5, so 13+5=18.
They appear to be 13 and 17

The Fibonacci sequence is infinite. The next two terms are 89 and 144.
This is called the Fibonacci sequence. The last two numbers in the sequence are added together to produce the next. Therefore, following 8 and 13 are: 8 + 13 = 21 13 + 21 = 34 21 + 34 = 55 34 + 55 = 89 55 + 89 = 144

This is a Fibonacci sequence with alternate terms omitted. The first two numbers in the Fibonacci sequence are 0 and 1, and each subsequent number is the sum of the previous two. (0),1,(1),2,(3),5,(8),13,(21),34,(55),89 The bracketed terms are the omitted terms. The next number would thus be 89
The next three numbers in the sequence are 23, 25, and 27.

Since the terms of the given sequence differ by different numbers, then the terms would start a new pattern, so that the other term of the sequence is 23.16 26 21 13 23 18 10...
There are many possible answers. One obvious one is 13, the next number in the Fibonacci Sequence that yields the golden mean.
13, 21 - it is the Fibonacci sequence
