73​

Answer 1

Answer:

28 is the missing

Answer 2

Answer:

Therefore, the required missing number in the following matrix is -41.

Step-by-step explanation:

STEP 1:

Given- The following matrix is given as:

             -7     1      28

             -4     17     8

              ?     56    73

To find- Find the missing number from the given matrix.

• We will solve the matrix by applying the rule:  sum(third column of 1st row + third column of 2nd row) × 2 + 1 and multiplying the succeeding numbers and so on, so as to get the total of each column in the third row.  

STEP 2:

According to the rule,

(28 + 8) × 2 + 1 = 36 × 2 + 1 = 72 + 1 = 73

(1 + 17) × 3 + 2 = 18 × 3 + 2 = 54 + 2 = 56

(-7 - 4) × 4 + 3 = -11 × 4 + 3 = -44 + 3 = -41

So, the missing number in the following matrix is -41.
