• -50
  
  Take a group of 3 numbers (2,7,-35) (7,12,-60) (5,10, ?)
  If the numbers of the group are (x,y,z), then z= -y*(y-x)
  So, -7*(7-2) =-7*5= -35
  -12*(12-7)= -12*5= -60
  -10*(10-5)= -10*5= -50

• 2 - 7 = - 5 7 * - 5 = - 35
  7 - 12 = -5 12 * -5 = -60
  5 - 10 = -5 10 * -5 = -50

• ANSWER : -50
  
  (2-7)*7= -35
  (7-12)*12 = -60
  (5-10)*10 = -50

• 2+5=7*-5=-35
  7+5=12*-5= -60
  5+5=10* -5=-50

• First divide the series in 3 numbers, nd then 7 *5=35,7-5=2... So ans is -50

• -50 is the answer
  bcoz
  2+5=7
  7+5=12
  5+5=10
  7*-5=-35
  12*-5=-60
  10*-5=-50

• 5*7=35
  5*12=60
  5*10=50
  ans is=50

• _50 bcoz 2+5=7 and 7* _5=_35 so 5+5=10 and 10*_5=_50

• Difference bwn 2 & 7 is -5 then 7* -5 is -35.
  7 & 12 is -5 then 12*-5 is -60.
  In the same way difference between 5 & 10 is -5 then 10* -5 is -50.
  So answer is -50.

• ans: -50
  sol : 2-7= -5, 7*-5= -35
  7-12=-5, 12*-5=-60
  5-10=-5, 10*-5=-50

• first divide 3 numbers into 1 set (2,7,-35) as one set , (7,12,-60) as one set (5,10,?) as one set
  Now see
  difference btw 1st num & 2nd num of each set is -5 , multiply -5 wth middle number of each set
  2 - 7 = -5 * 7 =-35
  7 - 12 = -5 * 12 = -60
  5 - 10 = -5 * 10 = -50
