Correct Answer: 40


Solution : Given:
43, 45, 42, 46, 41, 47, ?

Alternately add and subtract consecutive natural numbers starting from 2 from the previous number to get the next ones.
43 + 2 = 45; 45 – 3 = 42; 42 + 4 = 46; 46 – 5 = 41; 41 + 6 = 47; 47 – 7 = 40

Therefore, 40 is the required missing number. Hence, the second option is correct.
