Question

Every week Bob checks on his chickens and adds more grain to a hopper feeding them. The first week it is empty and he adds 218 lbs. ham The next week he finds 217 lbs grain remaining. He adds 3 lbs to the hopper. ham The next week he finds 218 lbs grain remaining. He adds 9 lbs to the hopper. ham The next week he finds 223 lbs grain remaining. He adds 16 lbs to the hopper. ham The next week he finds 231 lbs grain remaining. He adds 26 lbs to the hopper. How much grain will he find remaining next week?

Answer 1

every time the grain goes down it doubles,

218 - 217 = 1
217 + 3 = 220
220 - 218 = 2
218 + 9 = 227
227 - 223 = 4
223 + 16 = 239
239 - 231 = 8

so following that pattern

231 + 26 = 257
257 - 16 = 241

The answer is 241

Answer 2
