Vocabulary<br />
• geometric sequence – a sequence in which<br />
each term after the nonzero first term is found by<br />
multiplying the previous term by a constant<br />
called the common ratio, where r ≠ 0, 1.<br />
• common ratio – the number each term is<br />
multiplied by to find the next term.<br />
• geometric means – the missing term between 2<br />
given terms in a geometric sequence. To find<br />
the missing term, multiply the two terms that the<br />
missing number is between and take the square<br />
root.<br />
