Correct Answer: 447
Solution :
Given:
7, 56, 447, 3584, 28672
In the above-given series, multiply the previous number by 8 to get the next number.
7 × 8 = 56; 56 × 8 = 448 ≠ 447; 448 × 8 = 3584; 3584 × 8 = 28672
So, 447 is the wrong number as it doesn't follow the pattern. Hence, the fourth option is correct.
