Question

find the common difference of the AP 1/3q ,1 - 6q by 3q, 1 - 12q by 3q etc.​

Answer 1

Answer:

-2

Step-by-step explanation:

a1 = 1/3q

a2= 1-6q by 3q

a3 = 1- 12q by 3q

now

a2 - a1 = 1-6q by 3q - 1/ 3q = -2

a3 -a2 = 1 - 12q by 3q - 1-6q by 3q = -2

As differences in both cases are same therefore common difference = -2
