Step-by-step explanation:
The sequence is as follows :
-59 ,-67 ,-65 ,-53 ,-31 ,...
The first term = -59
The second term = -67
Common difference = second term - first term

To calculate the second term add (-8).
To calculate each additional term, increase the amount added by -8.
I think it’s either b or c
Angle between 16 and 18 = 90 + 55 = 145°
Percent discount = (original price - sales price) / original price
1250 - 900 = 350
350/1250 = 0.28
The percent discount is 28%.
