Show that the sequence 9,12,15,18,... is an A.P. Find its 16th term and the general term.

Explanation

To show that the sequence 9, 12, 15, 18,... is an Arithmetic Progression (A.P.), find its 16th term, and derive the general term, we can follow these steps:

### Step 1: Identify the sequence
The given sequence is:
\[ 9, 12, 15, 18, \ldots \]

### Step 2: Determine the common difference
To confirm that the sequence is an A.P., we need to find the common difference \(d\) between consecutive terms.
