How to determine if a sequence is geometric or not

The video tutorial discusses how to differentiate between geometric and arithmetic sequences. It explains that arithmetic sequences have a common difference between terms, while geometric sequences have a common ratio. The tutorial provides examples and verifies the type of sequence by calculating differences and ratios, concluding with the identification of a geometric sequence.

What is the first step in identifying whether a sequence is geometric or arithmetic?

• Find the sum of all terms.

• Label the terms with Ace of 1, Ace of 2, etc.

• Divide the first term by the last term.

• Multiply all terms together.

How can you determine if a sequence is arithmetic?

• By adding all terms together.

• By finding the common difference.

• By dividing the last term by the first term.

• By finding the common ratio.

What is the common difference in an arithmetic sequence?

• The consistent difference between consecutive terms.

• The difference between the first and last term.

• The product of all terms.

• The sum of all terms.

How do you identify a geometric sequence?

• By finding the common difference.

• By adding all terms together.

• By subtracting the last term from the first term.

• By finding the common ratio.

What is the common ratio in a geometric sequence?

• The product of all terms.

• The sum of all terms.

• The difference between the first and last term.

• The consistent ratio between consecutive terms.
