  3+7=27,
  4+5=32,
  5+8=60,
  6+7=72,

  actually I left the explanation part so as not to spoil the sport for other members who would try to solve the question.....
  anyway ,if it's expected then here's it
  
  1*2+2*3=8
  2*3+3*7=27
  3*4+4*5=32
  4*5+5*8=60
  5*6+6*7=72
  
  hence 6*7+7*8=98😎
  
  since all the nos are in sequence , fisrt operands are multiplied by 1....onwards and then both the operands are multiplied with each other and consequently added together.....👍

  1*2+2*3=8
  2*3+3*7=27 <----
  3*4+4*5=32
  4*5+5*8=60
  5*6+6*7=72
  
  hence 6*7+7*8=98😎

  Couldn't understand this '7' ... infect all of the red ones.

  Couldn't understand this '7' ... infect all of the red ones.

  see it's simple :
  2*3=6
  + 3*7=21
  6+21=27
  is it this that u wanted to know? or probably u might be thinking that the nos marked red aren't in sequential fashion....but that insequentiality is a part of ur challenge...😀

  He He He... Good One.
  
  Non Sequential numbers.....3, 7, 5, 8, 7...
  what make you think that next non-sequential number should be 8 to make answer as 6*7+7*8=98 ?

  it was there in ur question itself......and knew that it's right ...i had to insert only 6 in the structure ....that's why i have formatted the manually entered numbrs as bold...

  Hi i tried for 20 minutes and failed but my friend found it in five minutes.
  his answer:98
  Explanation :
  1)Add the two numbers
  2)Multiply the answer with first digit and subtract the same digit to answer.
  example :2+3=8
  1)2+3=5
  2)5*2=10
  3)10-2=8

  answer is 98...
  i found answer by the following,
  (2*3)+(2*1)=8
  (3*7)+(3*2)=27
  (4*5)+(4*3)=32
  (5*8)+(5*4)=60
  (6*7)+(6*5)=72
  here 1,2,3,4..etc are the order of equations
  so
  7+8=(7*8)+(7*6)=98
