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?

At Present Jane has Total Stickers = 251

Step-by-step 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
