Show that each of the progressions given is an AP. Find the first term , common difference and next term of given series
`(ii) 11 ,6, 1 ,-4 . . . `

Explanation

To show that the given series \(11, 6, 1, -4, \ldots\) is an Arithmetic Progression (AP), we need to check if the difference between consecutive terms is constant.

### Step 1: Identify the Terms
Let's denote the terms of the series:
- First term \(a_1 = 11\)
- Second term \(a_2 = 6\)
- Third term \(a_3 = 1\)
- Fourth term \(a_4 = -4\)
