+3, -3, +4, -3, +5, -3, (+6, -3, +7, -3...)
for 3: count all number if divisable by 3 (123= 1+2+3= 6, 3+3=6) for 5:end number is 5 or 0
0, 1, 1, 2, 3, 5, 8, 13, 21, 34... begin with 0, 1, 1, nd add the two previous numbers to get the next number. 1+1=2 1+2=3 2+3=5 3+5=8 5+8=13
If a number ends with 0, it is divisible by 10. If a number ends with 5 or 0, it is divisible by 5.
The rule is (-2, -5)

+3, -3, +4, -3, +5, -3, (+6, -3, +7, -3...)
for 3: count all number if divisable by 3 (123= 1+2+3= 6, 3+3=6) for 5:end number is 5 or 0
5-5-5--3-3--5-5--0--0-0---5-5-5--3-3--5-5--0
5-5-5--3-3--5-5--0--0-0---5-5-5--3-3--5-5--0
Any number ending with 0 or 5 is a multiple of 5 except 0 itself.
0, 1, 1, 2, 3, 5, 8, 13, 21, 34... begin with 0, 1, 1, nd add the two previous numbers to get the next number. 1+1=2 1+2=3 2+3=5 3+5=8 5+8=13
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...

The Importance of Fibonacci's series is that it helps people find more patterns 1+0=1 1+1=2 1+2=3 2+3=5 5+3=8 etc.
If a number ends with 0, it is divisible by 10. If a number ends with 5 or 0, it is divisible by 5.
