How to use the recursive formula to evaluate the first five terms

The video tutorial explains the concept of a recursive formula, demonstrating how to calculate subsequent terms using a given starting point. It walks through the process of finding the second and third terms by plugging in previous values, emphasizing the importance of understanding the recursive process. The tutorial concludes with a recap of the formula and its application.

What is the primary purpose of using a recursive formula in this context?

• To find the sum of all terms

• To determine each term based on the previous one

• To calculate the average of terms

• To identify the largest term

How do you find the second term in a recursive sequence?

• By using the first term in the recursive formula

• By multiplying the first term by a constant

• By adding a constant to the first term

• By dividing the first term by a constant

What is the value of the second term if the first term is 25 and the recursive formula is a_n = a_(n-1) - 5?

• 10

• 15

• 20

• 30

What is the value of the third term in the sequence if the second term is 20?

• 25

• 10

• 15

• 5

What pattern can be observed in the sequence as you continue applying the recursive formula?

• The terms decrease by 5

• The terms increase by 5

• The terms remain constant

• The terms double each time
