What number is needed to complete the pattern below? 5, 10, 3, 15, 20, 13, 25, 30, __?
Solution:
The given pattern is
5, 10, 3, 15, 20, 13, 25, 30, __
To solve the question, we have to find the progression of the series
We see that there are three alternate series
Here 1st, 4th and 7th numbers increase with 10
5 + 10 = 15
15 + 10 = 25
Here 2nd, 5th and 8th numbers increase with 10
10 + 10 = 20
20 + 10 = 30
Here 3rd, 6th and 9th numbers increase with 10
3 + 10 = 13
10 should be added to the 6th number to find the term which is missing.
13 + 10 = 23
Therefore, the number needed to complete the pattern is 23.
What number is needed to complete the pattern below? 5, 10, 3, 15, 20, 13, 25, 30, __?
Summary:
The number needed to complete the pattern 5, 10, 3, 15, 20, 13, 25, 30, __ is 23.
