Video Summary
Bruce's guess for kangaroo 20's color is incorrect. The pattern of the kangaroo colors repeats every three with different colors: X, Y, Z. Kangaroo numbers divided by three with a remainder one are color X, with a remainder two are color Y, and with no remainder are color Z. Calculations show kangaroo 2 is Y, 20 is Y, 202 is X, 1002 is Z, and 2021 is Y. Bruce guessed kangaroo 20 as blue (Z), but based on the remainder method, it should be Y. Therefore, the erroneous guess is for kangaroo 20.
