Alfred is practicing typing. The first time he tested himself, he could type 30 words per minute. After practicing for a week, he could type 33 words per minute. After two weeks he could type 36 words per minute. Based on this pattern, predict how fast Alfred will be able to type after four weeks of practice.

    So based on this, the words per minute is increasing by 3 words per week. Since he's already practiced 2 weeks, after practicing for another 2 weeks (giving a total of 4 weeks) his typing speed would increase by 6 more words (3*2) giving him a total of 42 words per minute.
