  1. It's (E), the letter O. K1 A2 N3 G4 A5 R6 O7 O8. The pattern is 8 letters long, so 2000 is divisible by 8, K is the 2001st letter and O becomes the 2007th letter.

  2. 2007/8 (8 = number of letters), we get 250-R7, the seventh letter is O, so the answer is O (E)

  3. It is E (O) since 2007/8 is 250R7 and the seventh letter of kangaroo is o.
