In the following number series, two numbers have been put with in brackets. Study the series carefully and select the correct alternative with respect to the series.
0, 1, 4, 9, (15), 25, 36, 49, (64), 81
Clearly, the above series is a combination of square of consecutive whole numbers, but the first bracket number, i.e. 15 is incorrect as it is not a perfect square, while the second bracket number 64 is correct, as $$(8)^2=64$$
Thus, the first bracketed number(from the left) is incorrect and the second is correct.
