Since there are only 4 terms in the sum, it's not too much work to expand it as
Alternatively, we can use the well-known formulas
These sums start at n = 0, so in our given sum we will keep track of the 0-th term separately:

Regular price of pillow = p
Mark down = 5% =
Amount of mark down = 0.05p
Amount after mark down = Regular price - Mark down amount
Amount after mark down = p - 0.05p
Taking p common = p(1-0.05) = p(0.95) = 0.95p
Two expressions that represent the sale price of the pillows are (p-0.05p) and 0.95p.
