Answer:
The ordered pair to represent the second term as an ordered pair is:
Explanation:
Background knowledge about the sequence function
A sequence is defined as the function whose domain is the set of natural numbers (counting numbers).
1, 2, 3, 4, .... n, ....
↓
a₁, a₂, a₃, a₄, .... aₙ, ....
Here,
1 gets mapped onto a₁,
2 gets mapped onto a₂, and so on
The numbers a₁, a₂, a₃, a₄, .... aₙ, .... are the terms of the sequence.
The number aₙ is the nth term of a sequence.
And the sequence function is denoted by {aₙ}.
Given the sequence
3, 9, 15, 21, ...
Here,
a₁ = 3 is the first term
a₂ = 9 is the second term
Thus, the ordered pair to represent the second term as an ordered pair is:
