Question

Mindy read 8 pages of her book the first day, 15 pages the second day, and 22 pages the third day. if the pattern continues , how many pages of her book will she read on the sixth day

Answer 1

Entirely impossible to know, there are an infinite number of sequences which have the terms 8, 15, and 22 for n=1,2,3 -you could say that if you wanted to give a "smart" answer and it would be true
otherwise 43 pages on 6th day I think

Answer 2

43 pages 8+7=15  15+7=22  22=7=29  29+7=36  36+7=43
