The answer is 4
9*8=72...7 and 2
7*2=14...1 and 4
1*4= 04....0 and 4
Well-done Oga Guobe, you want make we do little exercise in this hot afternoon

4

9x8=72 ie.7 and 2; 7x2=14 ie.1 and 1x4= 04. Ie.0 and 4

To solve this puzzle, let’s analyze the pattern of numbers in the top and bottom rows:

Top row: 9, 7, 1, 0
Bottom row: 8, 2, 4, ?

One possible logic is to look at the relationship between numbers in corresponding positions:

9 (top) - 8 (bottom) = 1

7 (top) - 2 (bottom) = 5

1 (top) - 4 (bottom) = -3


The differences don’t appear to follow a consistent rule. Another approach might involve adding or multiplying numbers in a certain pattern, but nothing straightforward emerges.

Without an apparent clear pattern, this might be an optical puzzle or use a hidden mathematical rule.

Maybe you should explain better on the steps I ought to have taken, I am even not sure if I took the wrong steps.

I have tried my best 😞

On closer inspection, this pattern can actually be solved by recognizing the following:

For each column, it appears that the bottom number is derived by subtracting the top number from 10. Let’s check this logic:

1. In the first column: 10 - 9 = 1


2. In the second column: 10 - 7 = 3


3. In the third column: 10 - 1 = 9


4. For the fourth column, applying this rule: 10 - 0 = 10



So, the missing number should be 10.

Final answer: 10

It looks like each number in the bottom row is actually calculated by subtracting the corresponding top number from 9 (not 10). Let’s verify with this approach:

1. First column: 9 - 8 = 1


2. Second column: 9 - 7 = 2


3. Third column: 9 - 1 = 8



So for the fourth column, following this rule:

9 - 0 = 9


The missing number should be 9.

Final Answer: 9
