How to Find Any Term of a Geometric Sequence
Identify the first term in the sequence, call this number a.; , Calculate the common ratio (r) of the sequence., Identify the number of term you wish to find in the sequence., The nth term is given by arn-1.
Step-by-Step Guide
-
Step 1: Identify the first term in the sequence
It can be calculated by dividing any term of the geometric sequence by the term preceding it. , Call this number n.
For example, if you wish to find the 8th term in the sequence, then n =
8. , Simply insert the values of a, r and n in this formula and evaluate the resulting expression to get the nth term. -
Step 2: call this number a.;
-
Step 3: Calculate the common ratio (r) of the sequence.
-
Step 4: Identify the number of term you wish to find in the sequence.
-
Step 5: The nth term is given by arn-1.
