Identify the given blood pressure (Bp) readings and determine the differences between consecutive readings.

Step 1: Identify the given blood pressure (Bp) readings and determine the differences between consecutive readings.
The given Bp readings are $160, 136, 128, 152, 148$ mmHg. These are recorded every hour.
Let $a_n$ be the Bp at hour $n$.
$a_1 = 160$ mmHg
$a_2 = 136$ mmHg
$a_3 = 128$ mmHg
$a_4 = 152$ mmHg
$a_5 = 148$ mmHg

Calculate the differences between consecutive terms:
