A Very Easy Number Sequence Puzzle (If You Figured It Out)


What is the next term in the following sequence?

7, 8, 5, 5, 3, 4, 4, ?


This type of puzzle is extremely easy once you found out the pattern involved. However, it can be frustrating to solve for some people.

To know the next digit, you must first figure out the underlying pattern of the sequence. Depending on your skill at spotting patterns or the number of puzzles you’ve solved, this can either be simple or difficult.

The answer is 6. Why? The numbers in the sequence correspond to the number of letters of the months of the year in English, starting with January. Therefore:

January has 7 letters.
February has 8 letters.
March has 5 letters.
April has 5 letters.
May has 3 letters.
June has 4 letters.
July has 4 letters.

The next term in the sequence represents the number of letters of “August”. As August has 6 letters, it can now be concluded that the next term is 6.

This is the complete sequence:

7, 8, 5, 5, 3, 4, 4, 6, 9, 7, 8, 8

  1. Oh la la 😢 I was thinking in an other way lol I didn’t relate it to months or their letters at all,instead I was looking for the relation between these numbers and so my guess was: 5. Why? And how? :
    7,8,5 =(7+1=8/ 8-3=5),
    (repeat the last number=5/ 5-2=3/ 3+1=4)
    (repeat the last number=4 and here where I thought It was the return to start point (4+1, just like 7+1=8)
    So: 7,8,5,5,3,4,4,5,2,2,0,1 😰😯😂
    Oh I feel embarrassed trying to explain the way I thought was right hahaha 😂😂😂
