1,2,3,5,8,13,21,34.....之數學規律

應該是1,1,2,3,5,8,13.....這叫斐波那契數列(Finbonacci sequence)他是意大利人,規律是:
一個加一個exp:1+1=2,1+2=3,2+3=5,3+5=8,5+8=13,8+13=21,所以之後是34,55,89,144...

1+2=3, 2+3=5, 3+5=8, 5+8=13, 8+13=21, 13+21=34, 21+34=55

1,4,9,16,25,36,49,64.....之數學規律
2,8,32,128,152.....之數學規律
2,4,6,8,10,12,14.....之數學規律
1,3,5,7,9,11,13,15.....之數學規律
7,15,23,31,39.....之數學規律
101,93,85,77.....之數學規律
1,1,2,3,5,8,13.....之數學規律
1,8,27,64,125.....之數學規律
0,2,6,12,20,30.....之數學規律
0,6,24,60,120,190.....之數學規律
3,12,27,48,75.....之數學規律
1,2,3,4,5,6,7,.....之數學規律

1,2,3,5,8,13,21,34.....
1st term+2nd term=3rd term
a2=1+1
a3=1+2
a4=2+3
a5=3+5

n th term + (n+1)th term= (n+2) term

下一個是 55

1+2=3, 2+3=5, 3+5=8, 5+8=13, 8+13=21, 13+21=34, 21+34=55

55,110,220,440,880,1760...................................................................................................
