Can you solve it?
2+3=8,
3+7=27,
4+5=32,
5+8=60,
6+7=72,
7+8=??  Choose the correct choice from the following choices:	A) 68	B) 78	C) 88	D) 98	E) 56
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   correct answer is 98)98
