Answer 2

Answer:

I think the question is not full. Each cash prize is 20 less than the preordering prize right? If so-

Step-by-step explanation: Sn = 700

n=7

d=-20

700=7/2[2a+6*-20]

700*2/7=2a-120

200=2a-120

2a=320

a=160

so the value of each cash prize is 160,140,120,100,80,60,40

Hope it was of help to you
