Concept explainers
To explain why the first term in geometric sequence must be non-zero.
Explanation of Solution
Given:
The given sequence is geometric sequence.
Calculation:
The geometric sequence is sequence of terms, whose ratio of successive terms is constant
The general term of the geometric sequence having first term
If the first term is zero, then all the other terms of the geometric sequence are zero for any common ratio
So that for well-defined geometric sequence, the first term and common ratio both are non-zero and if common ratio is equal to 1 then all the terms of the geometric sequence are equal to its first term.
