Find the 9th term of the G. P. 2, 1, `(1)/(2)`,….

Explanation

To find the 9th term of the geometric progression (G.P.) given as 2, 1, \( \frac{1}{2} \), ..., we can follow these steps:

### Step 1: Identify the first term (a) and the common ratio (r)
The first term \( a \) of the G.P. is the first number in the sequence:
\[ a = 2 \]

To find the common ratio \( r \), we divide the second term by the first term:
\[ r = \frac{\text{second term}}{\text{first term}} = \frac{1}{2} \div 2 = \frac{1}{4} \]
