"The combination is the seventh, ninth, and eleventh numbers in a sequence that begins 1,1,2,3,5,8,13, and so forth"
What is the combination?
I have a problem with this can you help?
The adjoning two numbers are added together.
1 + 1 = 2
1 + 2 = 3
2 + 3 = 5
and so on
This sequence is the Fibonacci sequence. Every number in this sequence is the sum of the two previous numbers:
1+1 = 2
1+2 = 3
2+3 = 5
3+5 = 8
5+8 = 13
The first seven numbers of the sequence are given, so to find the next four numbers add the two previous numbers.
Then you get:
So, the seventh, ninth, and eleventh numbers of this sequence are:
13,34 and 89
THANKS! I really didn't get it and everyone got it but me in my class.:D
