The next day, we had a lecture about Harmonic and Fibonacci sequences. Harmonic sequences are just the reciprocal of arithmetic sequence while Fibonacci sequence is a sequence that starts from either 1 or 0 and you can get the next term by adding the two preceding terms. We also discussed about the sum of an infinite geometric sequence. By the way, the formula for that is S= a1/1-r where r must be greater than -1 and less than 1.
The following day, we had a quiz, a ten item quiz that is good answering only in 30 minutes. I only got 15 out of 20 because of carelessness. I got the correct answer in the solution which is 206,668 but I wrote 20668 and the other one that I was wrong at is because of wrong analysis of problem, the problem asks for the sum but I solved for the nth term. What I did was very regretful. Next time, I will always triple check on my answers so that I will never have regrets on having low scores because of carelessness.
