A) 83
B) 40
C) 340
D) 170
Correct Answer: C
Solution :
\[9\,\,\times \,\,2\,\,+\,\,1\,\,=\,\,18\,\,+\,\,1\,\,=\,\,19\] \[19\,\,\times \,\,2\,\,+\,\,2\,\,\,=\,\,38\,\,+\,\,2\,\,\,=\,\,40\] \[40\,\,\times \,\,2\,\,+\,\,3\,\,=\,\,80\,\,+\,\,3\,\,=\,\,83\] \[~83\,\,\times \,\,2\,\,+\,\,4\,\,=\,\,166\,\,+\,\,4\,\,=\,\,170\] \[170\,\,\times \,\,2\,\,+\,\,5\,\,=\,\,340\,\,+\,\,5\,\,=\,\,\] Therefore, the number 340 is wrong in the series.You need to login to perform this action.
