(3*4)+2=14 (4*5)+3=23 (5*6)+4=34 (6*7)+5=47 (7*8)+6=62 (8*9)+7=79 Now add 0 and 1 alternatively..then we will get the series as follows.. (3*4)+2=14 (4*5)+3=24 (5*6)+4=34 (6*7)+5=48 (7*8)+6=62 (8*9)+7=80

if we do this series by none of the option is correct 1) 3*2=14 3+2 =(1+4)+0 2) 4*3=24 4+3=(2+4)+1 3)5*4=34 5+4=(3+4)+2 and so on 8*7= ??? 8+7 =(a+b) +5 than (a+b)=10 but none of the answer is matched

3*2=14 (3+1)*(2+1)=12+2 4*3=24 (4+1)*(3+1)=20+4 5*4=34 (5+1)*(4+1)=30+4 6*5=48 (6+1)*(5+1)=42+6 7*6=62 (7+1)*(6+1)=56+6 8*7=80 (8+1)*(7+1)=72+8 so ans is d)80
