The fibonacci sequence consist of the pattern 1,1,2,3,5,8,13?

Question

What is the ninth term in the pattern? I need help in this question

Answer 1

The next number is always the sum of the previous two.  You have seven of the terms listed.  So the eighth is 8+13 = 21.  And the ninth is 13+21 = 34.

Answer 2

34

Answer 3

The answer is 34, but to get it you add the 2 numbers before it.

Ex.

0+1=1  1+1=2  2+3=5  5+8=13  8+13=21  13+21+34

Ask me if you need more help.  I just did this for homework yesterday.

Answer 4

The last two numbers equals to the next number. For example, to find the third term, you'd add the first number and the second number (1+1=2).

The eighth term= 8+13=21

The ninth term=13+21= 43

Answer 5

In a Fibonacci sequence, the first two terms are 1, then each number thereafter is the sum of the two previous numbers. The next term would be 13 + 8 or 21, the ninth would be 21 + 13, or 34.

FYI, this sequence is neither arithmetic nor geometric, but does show up in nature in places like the arrangement of seeds in a sunflower. It was discovered by Leonardo of Pisa, also know as Fibonacci, an Italian mathematician of the 13th century.
