When Xiao Li reads a novel, she reads 74 pages on the first day, 82 pages on the second day, 71 pages on the third day, and 63 pages on the fourth day. The number of pages she reads on the fifth day is six pages less than the average number of pages she reads in the past five days. How many pages does Xiao Li read on the fifth day? I seek guidance from an expert.

The number of pages read on the fifth day was the number of pages read on the first day plus the number of pages read on the fourth day, which was 74 + 82 = 156 pages. Because the number of pages read on the fifth day was more than the sum of the previous four days, 156 > 4 × 71 + 3 × 63 + 2 × 82 + 1 × 74. Therefore, the answer was that Xiao Li read page 156 on the fifth day.
