Hi,
Here is your answer,
2 + 3 = 8
Now, we can write as 2 + 3 - 1 { Subtract 1 and we need to multiply by 1st number }
= 5 - 1
= 4 × 2
= 8
3 + 7 = 27
= 3 + 7 - 1
= 10 - 1
= 9 × 3 = 18
4 + 5 = 32
= 4 + 5 - 1
= 9 - 1
= 8 × 4
= 24
5 + 8 = 60
= 5 + 8 - 1
= 13 - 1
= 12 × 5
= 60
6 + 7 = 72
= 13 - 1
= 12 × 6
= 72
7 + 8 = ?
7 - 8 - 1
= 15 - 1
= 14 × 7
= 98.
Hope it helps you !

98
2+3=2*[3+(2-1)]=8
3+7=3*[7+(3-1)]=27
4+5=4*[5+(4-1)]=32
5+8=5*[8+(5-1)]=60
6+7=6*[7+(6-1)]=72
therefore
7+8=7*[8+(7-1)]=98
x+y=x[y+(x-1)]=x^2+xy-x
2+3=2*[3+(2-1)]=8
3+7=3*[7+(3-1)]=27
4+5=4*[5+(4-1)]=32
5+8=5*[8+(5-1)]=60
6+7=6*[7+(6-1)]=72
therefore
7+8=7*[8+(7-1)]=98
x+y=x[y+(x-1)]=x^2+xy-x
