Question

Jane had 27 stickers two weeks ago. She was buying stickers each day for those two weeks. She bought 3 stickers two weeks ago, and on each day she bought two more stickers than she bought on the previous day. How many stickers does she have now?

Answer 1

At Present Jane has Total Stickers = 251

Explanation:

Stickers Initially = 27

Jane bought stickers on 1st day = 3

Remaining days = 13

Each next day she bought 2 more stickers than the previous day, so:

Stickers bought in the last 2 weeks (14 days) = n+(n+2)+(n+2+2)+(n+2+2+2)+.............+(n+2(13))

here n =3

So:

Stickers bought in the last 2 weeks (14 days) = 3+5+7+9+11+13+15+17+19+21+23+25+27+29

Stickers bought in the last 2 weeks (14 days) = 224

At Present Jane has Total Stickers = Stickers Initially+ Stickers bought in the last 2 weeks (14 days)

At Present Jane has Total Stickers = 27+224

At Present Jane has Total Stickers = 251
