The table shows the distance Mr Chiam jogged each day over a period of 4 days. The distance Mr Chiam jogged follows a pattern. Based on the pattern, what is the distance Mr Chiam jogged on Day 8?
Day |
1 |
2 |
3 |
4 |
Distance jogged |
200 m |
375 m |
550 m |
725 m |
Pattern for the distance jogged:
Day 1: 200 + 0 x 175 = 200 m
Day 2: 200 + 1 x 175 = 375 m
Day 3: 200 + 2 x 175 = 550 m
Day 4: 200 + 3 x 175 = 725 m
Formula:
Distance jogged = 400 + (Day number - 1) x 175
Distance jogged on Day 8
= 200 + (8 - 1) x 175
= 200 + 7 x 175
= 1425 m
Answer(s): 1425 m
