Correct Answer: 18
Solution : Given: 21, 23, 20, 22, 19, 21, ?
In the above-given series, add 2 and subtract 3 alternately to each number to obtain the next number. 21 + 2 = 23; 23 – 3 = 20; 20 + 2 = 22; 22 – 3 = 19; 19 + 2 =21; 21 – 3 = 18
So, the missing number is 18. Hence, the second option is correct.
