Answer 2

Answer:

90 is the right answer . solution is given by many of our friends you can check , Now the question arises why not 72 so here i am going to tell you why 72 is wrong answer .

According to wiki 2*3=6, 3*4=12, 4*5=20, 5*6=30, 6*7=42 now we see there is written 9*8=72 which is wrong as per the pattern itself we have to take 9*10=90 Because, we see the pattern is let say x be the left hand side part then x*(x+1) = y
