## BeastMuch 2 years ago 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

1. waterineyes

Next term can be found by sum of previous two terms..

2. waterineyes

34 + 21 = 55 is the next term.. Like wise 55 + 34 = 89 is its next term.. Like wise find the 13th term here..

3. cwrw238

each term is formed by adding the previous 2 terms so the 10th term is 21 + 34 = 55 repeat this procedure 3 more times and you have the 13th term

4. BeastMuch

Wait I add the Fibonacci numbers? or te terms?

5. BeastMuch

Ohh Okay Thanks.

6. waterineyes

Fibonacci..

Okay So The Next Question Asks What is the sum of the first 13 terms in the Fibonacci Sequence? What Does That Mean?

30. BeastMuch

@cwrw238

31. brookester6

@BeastMuch it's 233 btw

32. brookester6

tht 13 number

33. BeastMuch

34. brookester6

35. BeastMuch

36. brookester6

umm not to sure bout tht one you'll have to give me a minute :)

37. BeastMuch

OKay Thanks.

38. cwrw238

12th term is 144 and 13th term is 233 the ratio is 233 / 144 which you can find on your calculator

39. BeastMuch

Would You Divide?

40. cwrw238

the sum of the first 13 terms is what it says 1+ 1 + 2 + ..... +144+ 233

41. cwrw238

233 divided by 144

42. BeastMuch

1.61805 ?

43. brookester6

yaw

44. cwrw238

1.61806 is more exact but they would probably accept 233/144 as the answer - just write them both !!!

45. BeastMuch

Haha OKay Thanks.
