11, 6, 1, -4, ....
11, 6, 1, -4, ....

Answer
A sequence in which each term differs from its preceding term by a constant is called an AP.
6 - 11 = -5
1 - 6 = -5
-4 - 1 = -5
clearly, the progression an AP.
The first term = 11
common difference = -5
The next term = -4 + (-5) = -9
6 - 11 = -5
1 - 6 = -5
-4 - 1 = -5
clearly, the progression an AP.
The first term = 11
common difference = -5
The next term = -4 + (-5) = -9
