Given the arithmetic sequence an = -1+7(n - 1), what is the domain for n?
Solution:
A domain is ‘all the values’ that go into a function.
The domain of a function is the set of all possible inputs for the function.
A progression is a sequence of numbers that follow a specific pattern.
An arithmetic progression (AP) is a sequence where the differences between every two consecutive terms are the same.
In any sequence, geometric, arithmetic or harmonic
n is the number of terms which starts from a1, a2 ….. an.
As we make use of n to count the number of terms, it can take values of natural numbers.
So the domain of n is N which is the set of natural numbers.
Here n ∈ N.
Therefore, the domain for n is N, the set of natural numbers.
Given the arithmetic sequence an = -1+7(n - 1), what is the domain for n?
Summary:
Given the arithmetic sequence an = -1+7(n - 1), the domain for n is N, the set of natural numbers.
