Answer 2

Correct question: if $\left[\begin{array}{cccc}8&16&32&1280\\4&8&16&?\\2&4&8&320\end{array}\right]$ what will be in place of the question mark​?

Answer:

In the given matrix, the number in place of the question mark will be 640.

Given

A matrix: $\left[\begin{array}{cccc}8&16&32&1280\\4&8&16&?\\2&4&8&320\end{array}\right]$

To Find,

The number in place of the question mark in the matrix.

Solution,

The method of finding the number in place of the question mark in the matrix is as follows -

We can observe that the numbers in the second row are half of the above numbers in the first row, such as $8 \div 2=4, 16\div 2= 8, 32\div2=16$.

Also, the numbers in the third row are half of the above numbers in the second row, such as $4\div2=2, 8\div 2=4,16\div2=8$.

So the number in place of the question mark will be half of 1280 and also the number will be double 320.

So the number will be $1280\div2=2*320=640$.

Hence, the number in place of the question mark in the matrix will be 640.
