Question

Choose the pattern follows the rule "+ 8".

  1. 4, 8, 12, 16, 20, ...
  2. 8, 10, 12, 14, 16, ...
  3. 120, 128, 136, 144, 152, ...
  4. 500, 505, 510, 515, 520, ...

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 to find a series of numbers that the pattern follows the rule "+ 8".
So here first we will analise all the series and then finalise which one is the best fit for the +8 rule.

The correct answer is: 120, 128, 136, 144, 152, ...


    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 a rule of +8. Now we will look at all the given patterns.
    1. 8, 10, 12, 14, 16, ...
    Here the pattern that is followed is +2, so this is not the correct option.

    2. 4, 8, 12, 16, 20, ...
    Here the pattern that is followed is +4, so this is not the correct option.
    3. 120, 128, 136, 144, 152, ...
    Here the pattern that is followed is +8, so this is the correct option.
    4. 500, 505, 510, 515, 520, ...
    Here the pattern that is followed is +5, so this is not the correct option.
    120, 128, 136, 144, 152, pattern follows + 8 rule. Because:
    120 + 8 = 128
    128 + 8 = 136……

    So the correct pattern is 120, 128, 136, 144, 152, ....

    Here we were given a rule of +8 and we were supposed to find the series which goes by this rule. 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. Here the rule of the pattern was to add 8, hence the series is 120, 128, 136, 144, 152, ...
