**Reiny**, Thursday, October 1, 2009 at 5:34pmYou are probably studying arithmetic sequences and series

let the first term be a

common difference is -10

and the number of terms is 5

S_{n}= (n/2)[2a + (n-1)d]

200 = (5/2)[2a + 4(-10)]

400 = 5[2a - 40]

400 = 10a - 200

600 = 10a

a = 60

So on the first day they must sell 60 tickets

check: 60 + 50 + 40 + 30 + 20 =

**M Bhatt**, Thursday, October 1, 2009 at 10:59pmassume that they will sell x tickets on the first day.

Sale on second day will be x-10

third day x-20

fourth day x-30

fifth day x-40

if we add them all up

x+x-10+x-20+x-30+x-40=200

5x-100=2==

5x=300

x=60

so they have to sell 60 on the first day

50 on the second

40 on the third

30 on the fourth

and 20 on fifth day.
