Ans.=1040
hw 1040?
I the above
3 2 => (3+2)*(3*2)=30 (correct)
7 3 =>(7+3)*(7*3)=210 but it was 410 there fore it is 200 extra and it is wrong
5 4 =>(5+4)*(5*4)=180 but it was 148 which is wrong.
8 5 =>(8*5)*(8+5)=520but it was 726 which is wrong
7 6=>(7*6)*(7+6)=546 (it is correct)
therefore the series is 1 right 3 wrong and 1 right...
following it
8 7 =(8*7)*(8+7)=840 +200 = 1040
this is as per my view...
