 By Panos Kalliantasis

Test your reasoning skills
Can you find the logical relation of the equations and then find the missing number?

 

If

2*4=10

3*5=19

4*6=30

Then

5*7=??

 Try to solve it yourself and discover the rule that the equations follow.



See the answer

 If the numbers of the equations are
A*B
The pattern is:
A*B =A*B +AP(2,4,6,8,...)
2*4= 2*4+2=10
3*5= 3*5+4=19
4*6 =4*6+6=30
5*7= 5*7+8=43
Correct answer is 43
