The table shows the distance Mr Ng jogged each day over a period of 4 days. The distance Mr Ng jogged follows a pattern. Based on the pattern, what is the distance Mr Ng jogged on Day 7?
Day |
1 |
2 |
3 |
4 |
Distance jogged |
200 m |
400 m |
600 m |
800 m |
Pattern for the distance jogged:
Day 1: 200 + 0 x 200 = 200 m
Day 2: 200 + 1 x 200 = 400 m
Day 3: 200 + 2 x 200 = 600 m
Day 4: 200 + 3 x 200 = 800 m
Formula:
Distance jogged = 400 + (Day number - 1) x 200
Distance jogged on Day 7
= 200 + (7 - 1) x 200
= 200 + 6 x 200
= 1400 m
Answer(s): 1400 m
