If `f:NtoR,` where `f(n)=a_(n)=(n)/((2n+1)^(2))` write the sequence in ordered pair from.

Explanation

To express the function \( f(n) = a_n = \frac{n}{(2n + 1)^2} \) in ordered pair form, we will calculate the values of \( a_n \) for \( n = 1, 2, 3, 4, \ldots \) and represent these as ordered pairs \( (n, a_n) \).

### Step-by-Step Solution:

1. **Calculate \( a_1 \)**:
\[ a_1 = \frac{1}{(2 \cdot 1 + 1)^2} = \frac{1}{(2 + 1)^2} = \frac{1}{3^2} = \frac{1}{9} \]
