Had me stumped on the prime number question, I found a different pattern where 15 = 6 * 2 + 3, 35 = 15 * 2 + 5, 77 = 35 * 2 + 7, etc, so the next number I got was 77 * 2 + 9 = 163 instead of 143

got the paperback version of the book 😍. it's also in chinese which i think is usually a better translation of japanese than translating japanese to english because it's easier to retain the elegance of the original text
