Find the rules and fill in the numbers ① 1, 1, 2, 3, 5, 8______ ②0.625，1.25，2.5，5，______ ． | Math enthusiast | Mathematical art

Find the rules and fill in the numbers ① 1, 1, 2, 3, 5, 8 ②0.625，1.25，2.5，5，．

(1) Because, 1 + 1 = 2, 2 + 3 = 5, 3 + 5 = 8, so 5 + 8 = 13; (2) because 0.625 × 2 = 1.25, 1.25 × 2 = 2.5, 2.5 × 2 = 5, so 5 × 2 = 10; so the answer is: 13; 10
