74.............????????..

Answer 2

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
