Answer:
The common difference of the progression is 3.
Step-by-step explanation:
Given:
First term of the AP = (a) = -8
Ratio of 7th and 9th term = 5:8
So,
General term of an AP, Tn= a+(n-1)d
Where 'd' is the common difference.
equation...(i)
equation...(ii)
According to the question.
⇒ ...cross-multiplying the terms.
⇒
⇒
⇒ ...subtracting 40d and adding 64 both sides.
⇒
⇒ ...dividing both sides with 3.
So the common difference of the progression is 'd' = 3.
