Answer 2

Answer:

option b)

Explanation:

• we are given the following series - 1 2 3 4 5 3 4 7 8 9 3 1 5 3 4 2 6 7
• In this, we can see that there are 4 threes. let us look at them one by one.
• The first 3 is the 3rd number and we see that it is preceded by 2 so it is eliminated.
• The second three is the 6th number and is preceded by 5 and followed by 4 and hence we keep it
• The third three is the 11th number and is preceded by 9 and hence eliminated
• The last three is in the 14th number and is also preceded by 5 and followed by 4 and hence we keep it
• Thus, in total we find 2 such 3s.
