Question

find the common difference of the ap: 1/2b,1-6b/2b,1-12b/2b

Answer 1

Answer:

Step-by-step explanation:

D=a2-a1

ie,d=1-6b/2b - 1/2b

=> 1-6b-1/2b

-6b/2b

=> -3 is the answer

Hope it helps

Answer 2

Answer:

The common difference of the AP is -3.

Step-by-step explanation:

The given AP is

$\frac{1}{2b}, \frac{1-6b}{2b},\frac{1-12b}{2b}$

The common difference of as AP is

$d=a_2-a_1$

$d=\frac{1-6b}{2b}-\frac{1}{2b}$

$d=\frac{1-6b-1}{2b}$

$d=\frac{-6b}{2b}$

$d=-3$

Therefore the common difference of the AP is -3.
