Explanation:

Step1: Recall even/odd rule

A number is even if divisible by 2 (last digit 0,2,4,6,8), odd otherwise.

Step2: Analyze 164

Last digit 4 (even), so 164 → Even.

Step3: Analyze 23

Last digit 3 (not even), so 23 → Odd.

Step4: Analyze 876

Last digit 6 (even), so 876 → Even.

Step5: Analyze 90

Last digit 0 (even), so 90 → Even.

Step6: Analyze 78

Last digit 8 (even), so 78 → Even.
