How to identify the rule of a sequence

The video tutorial explains how to determine the rule for a sequence of numbers with alternating signs. It covers the use of subscript notation, identifying patterns in the sequence, and finding rules for the numerator and denominator separately. The tutorial guides students through the process of using addition and multiplication to establish the rule, emphasizing the role of alternating signs in the sequence.

What is the first step in identifying a pattern in a sequence of numbers?

• Check for alternating signs

• Calculate the average

• Find the median

• Determine the mode

When writing rules for sequences, what notation is typically used?

• Subscript notation

• Fractional notation

• Superscript notation

• Decimal notation

How do you handle alternating signs in a sequence rule?

• By using -1 raised to a power

• By multiplying by 2

• By subtracting 1 from each term

• By adding 1 to each term

What is the rule for the numerator in the given sequence?

• n + 1

• n + 2

• n - 1

• n * 2

What pattern is used to determine the rule for the denominator?

• Add 2

• Multiply by 2

• Subtract 1

• Add 1
