Some numbers are missing from the number series below. Which option gives the missing numbers, from left to right?
3 5 _ 8 8 3 _ _ 8 8 3 _ 3 8 _ 3 5 _ 8 8
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → 3, 5, 3, 5, 8, 3
In a number series with blanks, the numbers that are given show a group that repeats. Here the group is 3, 5, 3, 8, 8 (5 numbers), written four times:
Copy 1: 3 5 3 8 8, so the blank here is 3
Copy 2: 3 5 3 8 8, so the blanks here are 5, 3
Copy 3: 3 5 3 8 8, so the blanks here are 5, 8
Copy 4: 3 5 3 8 8, so the blank here is 3
The blanks, in order, are therefore 3, 5, 3, 5, 8, 3.
