Correct Answer: 616
Solution :
Given:
730, 692, 654, ?, 578
Let's check the difference between each number of the given series –
Like, 730 – 692 = 38
And, 692 – 654 = 38
Thus, the common difference between the two numbers is 38.
Similarly, 654 – 38 = 616
616 – 38 = 578
Thus, the missing number is
616.
Hence, the third option is correct.
