Question

I do not understand this at all! Help please?? What is the 13th term in the Fibonacci Sequence?

Term 1 2 3 4 5 6 7 8 9
Fibonacci Number 1 1 2 3 5 8 13 21 34

Answer 1

To get the 10th term, add the last two terms (terms #8 and #9)

tenth term: 21+34 = 55

To get the 11th term, repeat, but do it for terms #9 and #10

eleventh term: 34+55 = 89

Keep going until you hit the 13th term

Answer 2

so 55+89= 144 is the 12th
89 +144= 233??

Answer 3

you got it

Answer 4

what does it mean by whats the ration of 13th and 14th?

Answer 5

find the 14th term

then divide the 14th term by the 13th term

Answer 6

377/144= 2.61805?
it says 5 decimal places so would that be right?

Answer 7

14th term: 377

13th term: 233 (NOT 144)

Ratio of 14th term and 13th term: (14th term)/(13th term) = 377/233 = 1.61803

Answer 8

Side note (probably optional), the number 1.61803 is a special number and it is known as the golden ratio (it's like pi where it goes on forever)

Answer 9

Ohh! thank you soo muuch!!!
