Correct Option is: (C) The wrong is 9.
Explanation:
The given sequence is 2, 3, 4, 4, 6, 8, 9, 12, 16.
It is required to find the wrong term in the given sequence.
The sequence - 2, 3, 4, 4, 6, 8, 9, 12, 16 has a combination of three series in it.
First:
1st, 4th, and 7th terms
That is,
2, 4, 9,....
Second:
2nd, 5th, and 8th terms
3, 6, 12, ….
Third:
3rd, 6th, and 9th terms
That is,
4, 8, 16,....
In each of the above sequences, each term is twice the preceding term.
But, in the first sequence, 9 is not twice 4.
Thus it is wrong, the correct number should be 8 (4 × 2).
