Question

What number comes Next?
2 + 3 = 8,
3 + 7 = 27,
4 + 5 = 32,
5 + 8 = 60,
6 + 7 = 72,
7 + 8 = ???
what is answer and how ?

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

(i) 2 + 3

= > 2 * 1 + 3 * 2

= > 2 + 6

= > 8.

(ii) 3 + 7

= > 3 * 2 + 7 * 3

= > 6 + 21

= > 27

(iii) 4 + 5

= > 4 * 3 + 5 * 4

= > 12 + 20

= > 32

(iv) 5 + 8

= > 5 * 4 + 8 * 5

= > 20 + 40

= > 60

(v) 6 + 7

= > 6 * 5 + 7 * 6

= > 30 + 42

= > 72.

(vi) 7 + 8

= > 7 * 6 + 8 * 7

= > 42 + 56

= > 98.

Therefore, the answer is 98.

Hope it helps!
