Finding the common difference of the sequence

The video tutorial explains how to find the common difference in a sequence, identify terms, and verify if a sequence is arithmetic. It demonstrates the calculation of the common difference using subtraction and confirms the arithmetic nature of the sequence by checking the consistency of the common difference between terms.

What is the first step in determining the common difference in a sequence?

• Subtract the first term from the second term

• Divide the first term by the second term

• Add the first two terms

• Multiply the first two terms

If the first term is 86 and the second term is 97, what is the common difference?

• -9

• 9

• 11

• -11

How do you confirm that a sequence is arithmetic?

• By checking if the sum of terms is constant

• By confirming the ratio of terms is constant

• By ensuring the product of terms is constant

• By verifying the common difference is consistent

What is the common difference if the sequence terms are 86, 97, 108?

• 11

• -11

• 12

• -12

Which of the following sequences is arithmetic?

• 5, 10, 20, 40

• 2, 4, 8, 16

• 1, 2, 4, 8

• 3, 6, 9, 12
