19 tháng 10 2023

Ta thấy quy luật tích của 2 số liền trước + 2 được số liền sau

1x1+2=3

1x3+2=5

3x5+2=17

Hai số hạng tiếp theo là

5x17+2=87

17x87+2=1481

20 tháng 10 2016

Ta có :

3 x 1 + 2 = 5

5 x 2 + 3 = 13

13 x 3 + 4 = 43

43 x 4 + 5 =177

177 x  5 + 6 = 891

891 x 6 + 7 = 5353

Vậy số cần tìm là 891
