Write an expression that gives the requested term.
The 14th term of the geometric sequence with first term 5 and common ratio
23/3/13
Step 1
A geometric sequence is a sequence of numbers in which each successive term of the sequence is the same constant multiple
of the preceding term. The common multiple is called the common ratio of the sequence.
For example, in the sequence 1, 2, 4, 8, ..., notice how each term is 2 times the preceding term. This an example of a
geometric sequence where 1 is the first term, 2 is the second term, 4 is the third term, 8 is the fourth term, and the common
ratio is 2. We can find all subsequent terms by simply multiplying by 2, but it would become tedious to figure out, say, the
100th term in this way.
Luckily there is a short cut formula below that we can use to find the nth term of a geometric sequence, where a, is the first
term of the sequence and r is the common ratio.
an=a₁-1
