Step-by-step explanation:

a) clearly, the sequence is created by subtracting 12 from one term to the next.

so, d = -12

a (= a1) = -5 (the first term is the start value)

the next 3 terms are then

-41, -53, -65

a28 = -5 + 27×-12 = -329

b) the sequence is created by adding 6 from term to term.

so, d = 6

a (= a1) = 8

the next 3 terms are

26, 32, 38

a77 = 8 + 76×6 = 464

The percentage of the discount will be calculated as:-

Percentage discount = ( 17 - 16.64 ) / ( 17 )
