Correct Answer: 68
Solution :
Given:
82, 79, 71, ?, 60, 57, 49
In the above-given series, subtract 3 and 8 alternately from the previous number to get the next number.
82 – 3 = 79; 79 – 8 = 71; 71 – 3 = 68; 68 – 8 = 60; 60 – 3 = 57; 57 – 8 = 49
So, 68 is the missing number of the series. Hence, the third option is correct.
