How many 3s are there in the following sequence which are neither preceded by 6 nor Immediately followed by 9?
93 66 39 59 37 89 16 39 63 9
Answer & explanation
Correct answer: option 3
We have,
93 66 39 59 37 89 16 39 63 9
So,
93 66 39 59 37 89 16 39 63 9
3's which are neither preceded by 6 nor immediately followed by 9, means we need to count the number of appearances of 3 not in the '6 3 9' pattern.
So, it appears two times as shown above.
