Question

2=3, 3=8,4=15,5=what

Answer 1

heya friend ,

Its quite easy  logical question 

Basically the Logic is  squaring the number and subtracting 1 from it see below,
 
2*2=4   =4-1==3[2=3]

3*3=9   =9-1==8[3=8]

4*4=16  =16-1==15[4=15]

and similarly 

5*5 =25  =25-1  == 24



So the answer is 24 !!

hope you got it and it  helps!!
