How do you find the nth term in an arithmetic sequence?

• Start with the first term and add the common difference (n-1) times

• Multiply the first term by n

• Subtract the common difference from the last term n times

• Add the common difference to the first term n times

How is the nth term of a geometric sequence calculated?

• Adding the first term to the common ratio raised to the power of n-1

• Multiplying the first term by the common ratio raised to the power of n

• Multiplying the first term by the common ratio raised to the power of n-1

Why is the exponent n-1 used in the explicit rule for geometric sequences?

• To compensate for the first term being a part of the sequence

• To adjust for the starting index of sequences

• Because you multiply the first term by the common ratio starting from the second term

• It represents the number of terms minus the first term

How does a recursive rule differ from an explicit rule?

• It defines each term based on the previous term

• It requires knowledge of all previous terms

• It only applies to arithmetic sequences

• It calculates each term independently
