Consider the given number pattern and identify the missing number.

  • A

    57

  • B

    67

  • C

    55

  • D

    68

The correct answer is 57.

Solution:

Considering the given number pattern.

Here, the numbers are decreasing.
So, to find the missing number, we first find the rule.

Note that:
87 – 10 = 77
77 – 10 = 67
67 – 10 = 57
57 – 10 = 47

So, the rule is "subtract 10".

Then, the missing number is 57.
