sum of 1890 is to be used to given seven ash prizes = 1890/7 = 207

each student gets = 207 rupees 

if 50 is less than the preceeding the value of total rupees = 50*7 = 350

1890-350 = 1540

each student gets = 157

by applying the formula of sum of terms we can find value of a,and take d=-50 and a comes out to be 420 so, value of prizes is 420, 370, 320, 270, 220, 170, 120.
