3601, 3602, 1803, 604, 154,36,12 |
A) 3602
B) 1803
C) 604
D) 154
E) 36
Correct Answer: D
Solution :
\[[3601+{{(1)}^{2}}]\times 1=3602\] |
\[\Rightarrow \]\[[3602+{{(2)}^{2}}\times \frac{1}{2}=1803\]\[\Rightarrow \]\[[1803+{{(3)}^{2}}\times \frac{1}{3}=604\] |
\[\Rightarrow \]\[[604+{{(4)}^{2}}+\frac{1}{4}=155\ne 154\] |
\[\Rightarrow \]\[[155+{{(5)}^{2}}]\times \frac{1}{5}=36\]\[\Rightarrow \]\[[36+{{(6)}^{2}}\times \frac{1}{6}=12\] |
