The video tutorial explains how to determine the recursive formula for a given sequence. It starts by analyzing the sequence to identify that it is not arithmetic but geometric. The first and second differences are calculated, leading to the derivation of a recursive formula. The constant B is found by substituting known values into the formula. Finally, the complete recursive formula is presented, allowing calculation of any term in the sequence using the previous term.

What type of sequence is being analyzed in the video?

• Arithmetic

• Fibonacci

• Geometric

• Harmonic

Why is the sequence not considered arithmetic?

• The terms are all prime numbers.

• The sequence is decreasing.

• The terms are not increasing.

• The differences between terms are not constant.

What is the significance of the second difference in the sequence?

• It shows the sequence is arithmetic.

• It is used to find the sum of the sequence.

• It indicates the sequence is geometric.

• It helps find the common ratio.

What is the value of 'm' in the recursive formula?

• 2

• 1

• 3

• 4

How is the value of 'B' determined in the recursive formula?

• By guessing

• By using the first term

• By solving an equation with known terms

• By using the last term

What is the recursive formula derived in the video?

• F(x) = F(x-1) + x - 1

• F(x) = F(x-1) + 2x - 1

• F(x) = F(x-1) + 3x - 1

• F(x) = F(x-1) + 2x + 1

What operation is performed on the term number in the recursive formula?

• It is added to the previous term.

• It is divided by 2.

• It is multiplied by 2.

• It is squared.

What is subtracted in the final step of the recursive formula?

• The value 2

• The value 1

• The previous term

• The term number

How can the recursive formula be used to find any term in the sequence?

• By using the first term only

• By using the last term only

• By using the previous term and the term number

• By using the sum of all terms

What is the purpose of deriving a recursive formula for a sequence?

• To predict future terms

• To determine if the sequence is finite

• To identify the first term

• To find the sum of the sequence
