Initial amount , a = $50 .
Increase in price , d = $25 .
We need to find the recursive relation of the sequence .
If we notice it is an arithmetic progression with common difference $25 .
Which means that difference between any two consecutive term is 25 .
So , T(n) - T(n-1) = 25
T(n) = T(n-1) + 25 .
Hence , this is the required solution .

Step-by-step explanation:
Have a good day
This is true, since ab=cd and ef must = ef the. Ab+ef = cd+ ef
Answer:
x=4
Step-by-step explanation:
if AB = 2x-5 and AC = 3x-9 and AB=AC then:
2x-5 = 3x-9
-x-5=-9
-x=-4
x=4
