Problema Solution
Alfred is practicing typing. The first time he tested himself, he could type 27 words per minute. After practicing for a week, he could type 29 words per minute. After two weeks he could type 31 words per minute. Based on this pattern, predict how fast Alfred will be able to type after four weeks of practice.
Answer provided by our tutors
First time: 27
After 1 week: 29
After 2 weeks: 31
We notice a pattern: Alfred's typing speed in increasing by 2, so now we have:
After 3 weeks: 31 + 2 = 33
After 4 weeks: 33 + 2 = 35
After 4 weeks Alfred will type with speed of 35 words per minute.
