Answer:
74 should come in place of the question mark
Step-by-step explanation:
The given series can be arranged as :
30, 36
40, 42
46, 52
58, 60
68, ?
Now, for finding the pattern of the given series :
36 - 30 = 6
42 - 40 = 2
52 - 46 = 6
60 - 58 = 2
Now, as we can see the difference between the second and first number is coming alternate 6 and 2.
So, we need to find a number whose difference with 68 is 6
⇒ 68 + 6 = 74 is our required number
Hence, 74 should come in place of the question mark
