Answer 2

Answer:

The value of $a-d$ is $8-a$.

Step-by-step explanation:

It is given that terms of AP are:

$4,a,b,-17$

We need to determine $a-d$ where common difference is $d$ and $a$ is first term.

AP is a sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value.

$d=a-4$

Hence, value of $a-d=4-(a-4)$

$=8-a$

Hence, $a-d=8-a$.
