**What is the next number in the sequence 9….3….1….1/3**?

## Answer

**1/9**

The sequence is 9, 3, 1, 1/3, 1/9.

## Explanation

The given sequence is a **geometric progression**.

The first term is 9 and the second term is 3. It is obtained by dividing 9 by 3.

Similarly, the third term (1) is obtained by dividing the second term (3) by 3.

Down the line, the fifth term is obtained by dividing the fourth term by 3.

So, 4^{th} term = 3^{rd} term / 3 = (1/3) / 3 = 1/ 9

Thus, the next number in the sequence 9….3….1….1/3 is 1/9.

The sequence is 9, 3, 1, 1/3, and 1/9.
