Số thứ 8 của dãy số đó là 68

Sâu bám vào 1 chiếc thuyền khi thuyền đó đang đón khách

gọi số cần tìm là ab

Số mới là a1b

Ta có:a1b=ab\(\times\)9

a0\(\times\)10+10+b=a0\(\times\)9+b\(\times\)9

a0\(\times\)(9+1)+10+b=a0\(\times\)9+b\(\times\)(8+1)

a0\(\times\)9+a0+10+b=a0\(\times\)9+b\(\times\)8+b

a\(\times\)10+10=b\(\times\)8(bớt cả 2 vế đi b và a0*9)

(a+1)\(\times\)10=b\(\times\)8

(a+1)\(\times\)5=b\(\times\)4(giảm 2 vế đi 2 lần )

Vậy a+1=4;b=5

a=4-1=3

Ta được số :35
