Question

solve this matrix..
12 15 21
8 7 26
? 41 34

Answer 1

The missiong value in the matrix is 51.

Step-by-step explanation:

In the following given matrix the first row is represented by the numbers;

12, 15 and 21

And the last row is represented by the numbers;

?, 41 and 34

After analyzing the first and last row of the matrix we observe that;

34 - 21 = 13

41 - 15 = 26

This shows that the first difference between the third and first row can be written as;

$13 \times 1 =13$

$13 \times 2=26$

So, we can conclude that;

x - 12 = $13 \times 3$

x - 12 = 39

x = 39 + 12 = 51

Hence, the missiong value in the matrix is 51.
