Answer: 25

Explanation:

Start with the first number, which is 3.

Add (N−1) times the common difference of 4.

Set the sum equal to 99, the value of the last number in the sequence.

Solve the equation for N by isolating it.

Divide both sides of the equation by 4.

N is equal to 25, representing the position of the last number in the sequence.
