Understanding the Fibonacci Sequence

The video tutorial explains how to find the first seven terms of a sequence using a recursive formula, specifically focusing on the Fibonacci sequence. It demonstrates the calculation of these terms and highlights the significance of Fibonacci numbers in nature, such as in flowers and pinecones. Additionally, the video explores the relationship between Fibonacci numbers and the golden spiral, encouraging further exploration of the sequence.

What is the recursive formula for the Fibonacci sequence?

• A(n) = A(n-1) - A(n-2)

• A(n) = A(n-1) * A(n-2)

• A(n) = A(n-1) + A(n-2)

• A(n) = A(n-1) / A(n-2)

What are the first two terms of the Fibonacci sequence?

• 0 and 1

• 1 and 1

• 2 and 3

• 1 and 2

How is the third term in the Fibonacci sequence calculated?

• By dividing the second term by the first term

• By adding the first and second terms

• By subtracting the first term from the second term

• By multiplying the first and second terms

What is the fifth term in the Fibonacci sequence?

• 3

• 5

• 8

• 13

What pattern is observed in the Fibonacci sequence?

• Each term is the product of the two preceding terms

• Each term is the difference of the two preceding terms

• Each term is the sum of the two preceding terms

• Each term is the quotient of the two preceding terms

Which of the following is a Fibonacci number often found in nature?

• 6

• 4

• 8

• 10

How many petals does a flower typically have if it follows the Fibonacci sequence?

• 4

• 5

• 6

• 7

What is the significance of the Fibonacci sequence in nature?

• It determines the color of flowers

• It appears in the number of petals and spirals

• It dictates the height of trees

• It controls the growth rate of plants

What is the golden spiral?

• A spiral based on the harmonic sequence

• A spiral based on the geometric sequence

• A spiral based on the arithmetic sequence

• A spiral based on the Fibonacci sequence

How can the Fibonacci sequence be used to approximate the golden spiral?

• By creating squares with side lengths equal to Fibonacci numbers

• By creating circles with diameters equal to Fibonacci numbers

• By creating triangles with sides equal to Fibonacci numbers

• By creating rectangles with areas equal to Fibonacci numbers
