Question

Find the missing term that should be placed in place of ? for a logical pattern given below.



\begin{tabular}{|c|c|c|} \hline 7 & 22 & 5 \\ \hline 5 & 9 & 11 \\ \hline 9 & 11 & 15 \\ \hline 38 & 77 & \( ? \) \\ \hline \end{tabular}

• A. $120$
• B. $55$
• C. $160$
• D. $83$

Answer 1

The correct option is C $160$

In the first column,
$(9\times 5)-7=38.$
In the second column,
$(11\times 9)-22=77.$
Similarly, in the third column,
$(11\times 15)-5=160.$

Hence, missing number is $160.$
