5 =5 Hence, 6"-1 is divisible by 5 is (10.). for n=1 Part 2: Assume that 6" - 1 is divisible by 5 for n-k21 6* -1 is divisible by 5 6*+1 -1 is divisible by 5 6*+1 -1= (11.). (12.). = [(6 – 1)- 6*]+ (6* - 1) = %3D %3D By divisibility definition, 5. 6* and 6* - 1 are divisible by 5. Therefore, their sum is also divisible by 5. The given divisibility statement, 6" - 1 is divisible by 5, has satisfied the two conditions of the (13.) positive integers n Hence, 6" - 1 is divisible by 5 for all
