the height of a plant was 204 millimeters. after one week, it grew by 33 millimeters, and after 3 more weeks, the new height of the plant was 282 millimeters. how much did the plant grow in 3 weeks?

Answer 1

t=0 204 mm

t=1 237 mm

t=3 ? about 280? 270?

t=4 282 mm

it grew 33 mm in 1 week

it grew 282-204 = 78 mm in 4 weeks

it's growth rate is slowing down

204+33 = 237

237+45=282

33, 24, 15, 6 are the decreasing weekly increases

204 in week 0

204+33 = 237 in week 1

237+24 = 261 in week 2

261+15 = 276 in week 3

276+6 = 282 in week 4
