What is the rule for the Fibonacci sequence?

The rule of the Fibonacci sequence is simple. Take the previous number in the sequence, and add it to the current number. The sequence starts with 0 and 1. 0, 1 So, add 0+1=1. The sequence now contains three numbers. 0, 1, 1 Now, add 1+1=2. This brings us to four numbers. 0, 1, 1, 2 Add 1 and 2. (1+2=3) 0, 1, 1, 2, 3 Now it gets a bit tricky. Add 2+3=5, so the next number is 5. 0, 1, 1, 2, 3, 5 Continue to add the numbers accordingly. (3+5=8) 0, 1, 1, 2, 3, 5, 8 Proceed. 0, 1, 1, 2, 3, 5, 8, 13, 25, 38, 63, 101, 164...


What is negative 1 plus 1 plus 2 plus 3 plus 5 equal?

-1+1+2+3+5= 10 First, you move 1 left of "0", which is -1. Then, you move 1 digit to the right, which puts you back at "0". Add 2, add 3, and add 5. The sum is 10.


How do you add addition fractions?

If you mean things like 1/5 + 2/5, you just add the top numbers together, (in this case, 1+2) and because the bottom number is the same number, you just keep it the same (don't add the bottom numbers) so the answer to 1/5 + 2/5 is 3/5.


How do you calculate numbers in the sequence 1 2 5 26?

Why is the next number 47 in the sequence 2 5 11 23?

To get from 2 to 5 you are multliplying 2 by 2 and adding 1. The difference is 3. Now, to get from 5 to 11 you do the same thing - multipy 5 by 2 and add 1 to get 11. That's what you do to 23. Multlipy by 2 and add 1 to get 47.
