Question

if,
2+3 =13
3+4 =25
4+5 = 41
then
5+6 =

Answer 1

The equations in the question follow the following formula

a + b = (2 x a x b) + 1

So we can get the results as follows;

2 + 3 = (2 x 2 x 3) + 1 = 12 + 1 = 13

3 + 4 = (2 x 3 x 4) + 1 = 24 + 1 = 25

4 + 5 = (2 x 4 x 5) + 1 = 40 + 1 = 41

Therefore,

5 + 6 = (2 x 5 x 6) + 1 = 60 + 1 = 61.

Hence answer is

5 + 6 = 61

Answer 2

the answer is 61 ....
as , a+b=2×a×b
so, 2+3=2×2×3+1=12+1=13
3+4=2×3×4+1=24+1=25
4+5=2×4×5+1= 40+1=41
So, 5+6= 2×5×6+1=60+1=61 ..
