1
A sequence is GEOMETRIC if the ratios of
consecutive terms are the same.
ex. 1, 2, 4, 8, 16, 32
2 is the common ratio.
an1 an ? r
a1 is the first term r is the common ratio
2
ex. 5, 1, 0.2, 0.04 Is this a geometric
sequence?
Find the common ratio (r).
a1 ? an 1 ?
Ex. a1 7 d 2 Write the first 4 terms
of the sequence.
3
Ex. a1 7 d 2 Write the first 4 terms
of the sequence.
Ex. a1 3 r 4 Write the first 4 terms
of the sequence.
Ex. a1 7 ak 1 -¾ ak Write the first
4 terms of the sequence.
