Eitan posted a video on the internet which only received approximately 100 views per day for
the first 365 days after it was posted. however, on the 366th day, eitan's video began to receive
a greater following: the total number of views grew at a rate of 25% per day. compared to the
number of views eitan's video received in the first 365 days, how many more views did his video
receive in the 7-day period after the first 365 days?
25 and -31
notice that if all the negatives were positive, you would have the arithmetic sequence 1, 7, 13, 19, on and on, adding 6 every time. so basically we have a geometric and arithmetic sequence combined, with the geometric sequence making it positive, and negative, and the arithmetic sequence adding 6 every time. this means the answer(s) are 25 and -31.
the answer would be 8 do you need an explanation?
