| Direction: In the following number series only one number is wrong. Find out the wrong number. |
| 485 494 660 1192 2281 4130 |
A) 660
B) 1192
C) 494
D) 485
E) 2281
Correct Answer: A
Solution :
The series is\[485+{{(3)}^{2}}=494\], \[494+{{(13)}^{2}}=\mathbf{663}\],\[663+{{(23)}^{2}}=1192\], \[1192+{{(33)}^{2}}=2281,\text{ }2281+{{(43)}^{2}}=4130\], Hence, it should be 663 in place of 660.
