Question

Write the missing numbers in this pattern.
12, 15, ___, 21, ____, 27

  1. 18, 23
  2. 18, 24
  3. 17, 25
  4. 17, 24

hintHint:

In mathematics, a number pattern is a series of integers that occur in a specific order. Patterns often describe the inverse relationship between numbers. Patterns can also be used to describe numerical sequences. Here we have given a series of 12, 15, ___, 21, ____, 27 and we have to find the missing term in this series.
We will first find the rule used in this pattern and then find the missing terms.

The correct answer is: 18, 24


    So as we know that a pattern or sequence in a series of numbers is called a number pattern. Generally, this pattern builds a connection between all integers.
    Some numerological pattern types are:
    There are two typical patterns for number sequences:
    • Arithmetic Sequences
    • Geometric Sequences
    The following are some examples of Number Patterns' unique sequences:
    • Square Numbers
    • Cubic Sequence
    • Triangular Numbers
    • Fibonacci Numbers
    We have been given the series 12, 15, ___, 21, ____, 27. The rule used in this is:
    15 - 12 = 3
    The difference between each number is 3. The rule for this pattern is to add 3 each time. Then the missing number in the pattern:
    15 + 3 + 18
    21 + 3 = 24

    Here we were given a series of numbers and we have to find the missing term in the series. There are numerous different sorts of number patterns. They could be a series of even or odd numbers, multiples of a specific number, ascending or descending, etc. So the missing terms are 18 and 24 respectively.
