I need steps pleasee Answer by ikleyn(52787) (Show Source):
What he has each day (at the end of each day) is shown in this table
Day 1 2 3 4
Amount 400 400-24 400-2*24 400-3*24
This sequence is an Arithmetic progression (AP) with the first term = 400 and the common difference d = -24.
What he will have at the end of the 17-th day, is the 17-th term of this progression
= + (17-1)*d = 400 + 16*(-24) = 400 - 16*24 = 16 kilograms of flour. ANSWER
