Question

A skier has decided that on each trip down a slope, she will do 2 more jumps than before. On her first trip she did 6 jumps. Derive the sigma notation that shows how many total jumps she attempts from her fourth trip down the hill through her twelfth trip. Then solve for how many total jumps she attempts from her fourth trip down the hill through her twelfth trip.

Answer 1

Answer:

180

Step-by-step explanation:

I'll just manually compute this one. Every attempt she will add 2 more jumps.

Attempt Jumps Accumulated Jumps

1 6 6

2 8 14

3 10 24

4 12 36

5 14 50

6 16 66

7 18 84

8 20 104

9 22 126

10 24 150

11 26 176

12 28 204

Total jumps from 4th trip through 12th trip: 204 - 24 = 180 jumps
