Arithmetic Sequences and Their Terms

The video tutorial explains how to determine the terms of an arithmetic sequence using a given formula. It walks through calculating the first four terms, listing them, and finding the common difference. The tutorial emphasizes the arithmetic sequence formula and demonstrates how to identify the common difference through subtraction of consecutive terms.

What is the value of the first term in the sequence?

• 0

• 2

• 5

• -5

How do you calculate the second term of the sequence?

• Add 5 to the first term

• Divide the first term by 2

• Subtract 5 from the first term

• Multiply the first term by 2

What is the value of the second term in the sequence?

• -3

• 2

• 5

• 0

What operation is performed first when calculating the third term?

• Division

• Multiplication

• Subtraction

• Addition

What is the value of the third term in the sequence?

• 2

• -8

• -3

• 5

What is the value of the fourth term in the sequence?

• 2

• -8

• -13

• -3

Which of the following lists the first four terms of the sequence correctly?

• 2, -3, 8, -13

• 2, -3, -8, -13

• 2, 3, 8, 13

• -2, -3, -8, -13

What is the common difference in this arithmetic sequence?

• 0

• -5

• 10

• 5

How can the common difference be identified from the sequence formula?

• By looking at the constant term

• By identifying the coefficient of n

• By identifying the coefficient of (n-1)

• By looking at the first term

How can you verify the common difference using two consecutive terms?

• Add the two terms

• Divide the second term by the first

• Multiply the two terms

• Subtract the first term from the second
