Answer 1

The given function notation \( f(n) = n^2 \) indicates that the function produces the square of the term \( n \). To find which sequence corresponds to this function, we can evaluate the function for several integer values of \( n \):

• For \( n = 1 \), \( f(1) = 1^2 = 1 \)
• For \( n = 2 \), \( f(2) = 2^2 = 4 \)
• For \( n = 3 \), \( f(3) = 3^2 = 9 \)
• For \( n = 4 \), \( f(4) = 4^2 = 16 \)
• For \( n = 5 \), \( f(5) = 5^2 = 25 \)

Putting these values together, we get the sequence: \( 1, 4, 9, 16, 25 \).

Therefore, the correct response is:

\( a_n = 1, 4, 9, 16, 25 \dots \)
