Q. What is the next number of the following sequence
2,2,12,12,30,30,?,?

• 1st term = 2 = 1^2 +1
  2nd term = 2 = 2^2 -2
  3rd term = 12 = 3^2 +3
  4th term = 12 = 4^2 -4
  5th term = 30 = 5^2 +5
  6th term = 30 = 6^2 -6
  So,
  7th term = 7^2 +7 = 56
  8th term = 8^2 -8 = 56
  
  So, next two terms will be : 56,56 .
  
  Thanks to All..:-):-)

• answer is 56
  because 2+10=12
  12+18=30
  30+26=56
• 12 years agoHelpfull: Yes(18) No(4)
• 2+10=12
  12+18=30(10+8=18, 8 increment)
  30+26=56(18+8=26, 8 increment)
  so answer is 56,56

• 56,56.bcz diff of 1st 2 nd 1st 12 is 10.den diff of 1st 12 nd nd 1st 30 is 18.hence no of diff increases in 8 mre than prv diff i.e.(18-10)=8,so the same way diff b/w 56 nd 30 is 26.in dis case also diff b/w 18 nd 26 is again 8 i.e.(26-18)=8.

• 1*2=2
  3*4=12
  5*6=30
  7*8=56
• 10 years agoHelpfull: Yes(2) No(0)
• 1*2,2*1,3*4,4*3,5*6,6*5,7*8=56,8*7=56

• answer is 56, 56.
  solution is very simple:-
  1*2=2
  2*1=2
  3*4=12
  4*3=12
  5*6=30
  6*5=30
  7*8=56
  8*7=56
  
  
  second solution is:-
  1^2 +1=2
  2^2 -2=2
  3^2 +3=12
  4^2 -4=12
  5^2 +5=30
  6^2 -6=30
  7^2 +7 = 56
  8^2 -8 = 56
  
  third solution is:-
  add 0 and then add multiples values of 10, 18, 26 iincreamenting them by 8 respectively. i.e.
  2+0=2
  2+10=12
  12+0=12
  12+18=30
  30+0=30
  30+26=56
  56+0=56
  and so on.

  differences are 10,8,6..
• 12 years agoHelpfull: Yes(1) No(20)
• pattern (n^2+n),(n+1)^2-(n+1)
  so, 7^2+7=56 and 8^2-8=56
  hence ans is 56,56

  2+2=4
  4+6=10
  10+2=12
  similarly 30+30=60
  60+6
  66

  difference is 0 10 0 18
• 9 years agoHelpfull: Yes(0) No(0)
• 12-2=10 then
  30-12 =18
  hence difference is 8
  so 30+26 =56

• 2*1=2
  2*6= 12
  12 *1= 12
  6*5=30
  30*1= 30
  so there are prime numbers are 2,3,7,9,11,13,17.........
  we take
  
  6*2=12
  6*5=30
  6*9=54
  another is this ques has many possible answers, solve these type of ques by the given options
