• To get from 4 to 12, you use the following formula. 12 = (4 squared)/2 + 4.
  
  Continue on with (X^2)/2 + X.
  
  So (84^2)/2+84=3612

• answer=3612
  Solution:
  (r*(r/2))+r
  (4*(4/2))+4=12
  (12*(12/2))+12=84
  (84*(84/2))+84=3612

• 4 == 1 2 2 4
  
  take last two ( 2 & 4)--->> (2+1)*4==12
  
  12 == 1 2 3 4 6 12
  
  take last two (6 & 12)----> (6+1)*12==84
  
  84 ==1 2 ......... 42 84
  
  take last two (42 & 84)----> (42+1)*84== 3612
  
  correct me if i m wrong plzzzzzzzzzzzzzzzzz....
  thankxxxxxxxxxxxxxxxxxx :-)

• 1008
  coz 4*3=12, 12*7=84, 84*12=1008

• 4*3=12
  12*(4+3)=84
  84*(12+7)=1596
• 10 years agoHelpfull: Yes(0) No(6)
• 1596
  As 4*3=12
  4+3=7*12=84
  so 7+12=19*84=1596

• difference between 4 and 12 =8
  difference between 12 and 84=72
  so 8*7=72
  7*6=42
  so 84+42=126

• 4 12 84 252
  exp-
  4 12 84 252
  *3 *7 *3 *7
  4 to 84 is the multiplication of 3,7 i.e 21
  same from 12 to 252 is *7*3=21
  21*12=252

• Here,term being squared is from the product of last pair, and a number one less to that term is subtracted from it.
  
  As, in first term we have 4×3=12
  
  So for next,squaring of 3,subtracted by a number one less i.e. 2= 3^2-2=9-2=7
  
  So 12×7=84,similarly for next term to obtain squaring of 7 and subtracted by 6, we get 43
  
  84×43=3612
