Answer:

Step-by-step explanation:

The formula for finding the nth term of an AP is aₙ = a + (n-1)d. In this formula, 'a' is the initial term in the arithmetic sequence and 'd' is a common difference. These two values can be either a positive or a negative integer. This is because the initial value of the sequence may be a negative value and the difference between any two numbers can also be a negative integer. However, 'n' is the number of terms in the sequence. We never use negative integers to count anything. Negative numbers are not counting numbers. Counting begins with the number '1' and increases gradually in the increments of one. All the counting numbers are natural numbers. So, the value of 'n' in this formula can never be a negative integer.
