Question

2+3=8,3+7=27,4+5=32,5+8=60,6+7=72,7+8=?

Answer 1

2+3=8  ->  2*3+2     ->  2*3+2*1    -> 6+2

3+7=27 ->  3*7+6    ->  3*7+3*2    -> 21+6

4+5=32 ->  4*5+12  ->  4*5+4*3    ->20+12

5+8=60 -> 5*8+20  ->  5*8+5*4   ->40+20

6+7=72 -> 6*7+30   ->  6*7+6*5   ->42+30

x+y= (x*y)+(x*n) where "n" being the next consecutive natural number.

7+8 = (7*8) +(7*6) = 98

Answer 2

(2+3)x2 -2 = 5x2-2=10-2=8
(3+7)x3-3= 10x3-3= 27

similarly
(7+8)x7-7= 15x7-7= 105-7= 98 answer
