Q:
# What Is the "Nth" Term in a Mathematical Equation?

**The "Nth" term in a mathematical equation is used to represent an unknown position in a geometrical sequence.** A geometric sequence follows a specific mathematical pattern to create a series of numbers. When a sequence is given and the user is asked to find the next value, this formula can be used to solve for the geometric pattern.

To begin solving a problem using this mathematical equation, first determine the relationship between the known factors. For instance, what is the relationship between 3, 6, 9 and 12?

If the first term is three times one, the second term is three times two, the third term is three times three, and the fourth term is three times four, then the Nth term is 3n.

Using the sequence of the Nth term equals 3n, the fifth term would be three times five. So, the next factor in the sequence 3, 6, 9, and 12, is 15.
