7
The next number in the sequence is 18. It's +1, +2, +3, +4, ....
The next number is 4, followed by -2
8
243
The sequence is taking half of the number and adding it to that number, 3/2 = 1.5, 3 + 1.5 = 4.5, the next number in the sequence is 15.1875

8 -1 then +3

For an integral sequence the next number is 6 (add 5 subtract 7 pattern).

64. It's the sequence f(n) = n^3
Each number is being added to the one before it. So, 5+3=8. 8 is the next number.
Fibonacci found a way to present mathematical numbers so that each number in the sequence is the sum of the two previous numbers. For example, if the sequence starts at 0 and 1, then next number in the sequence is 1, the next number would be 2, and then the next number would be 3, and then 5.
You add the last two numbers together to get the next number, and 3+5=8, so the answer is 8!
