Find the Domain a(n)=4n-2

Problem

a(n)=4*n−2

Solution

1. Identify the type of function or sequence provided. The expression a(n)=4*n−2 represents a linear function or an arithmetic sequence.

2. Determine the context of the variable n In the context of a general function ƒ(n) the domain is the set of all real numbers ℝ because there are no square roots of negative numbers or denominators that could be zero.

3. Consider the context of a sequence. If a(n) represents a sequence, the domain is typically restricted to the set of natural numbers {1,2,3,…} or non-negative integers {0,1,2,…}

4. State the standard domain for a linear expression. Without specific constraints indicating it is a sequence, the domain is all real numbers.

Final Answer

Domain:{n|n∈ℝ}
