Question

# Write the missing numbers in this pattern.

12, 15, ___, 21, ____, 27

- 18, 23
- 18, 24
- 17, 25
- 17, 24

Hint:

### 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.
