6. Ramilo is the track and field representative of the Maginoo High School for the Palarong Pambansa. He begins training by running 5 miles during the first week, 6.5 miles during the second week, and 8 miles on the third week. Assume this pattern continues, how far will he run on the fourth week? A9 miles B. 9.5 miles C. 10.5 miles D. 11 miles
Answers
Answer:
Option is A 9 miles
Given: The distance run during the first week = 5 miles
The distance run during the second week = 6.5 miles
The distance run during the third week = 8 miles
To find: The distance Ramilo will run on the fourth week
Solution: First, we need to check the difference between the distance covered by Ramilo every consecutive week.
The distance run during the second week - the distance run during the first week = (6.5 - 5) miles = 1.5 miles.
The distance run during the third week - the distance run during the second week = (8 - 6.5) miles = 1.5 miles.
As such, we see that Ramilo is maintaining an arithmetic progression since the difference is equal in both cases.
An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant.
Hence, the distance run during the fourth week = (8 + 1.5) miles = 9.5 miles.
Answer: Option B. 9.5 miles
