• difference between 12 and 2 is 10 and the 30 and 12 is 18.
  the difference between 18 and 10 is 8.
  so, we have the next number with difference of 18+8=26
  so 30+26=56.

• ANS: 58
  2,2,12,12,30,30,56,56
  12-2=10
  30-12=18 DIFF OF 18 AND 10=8
  56-30=26 ; 26-18=8
• 10 years agoHelpfull: Yes(1) No(2)
• 1^2+1,3^2+3,5^2+5,7^2+7
  answer is 56
• 10 years agoHelpfull: Yes(1) No(1)
• 1 * 2 = 2
  3 * 4 =12
  5 * 6 = 30
  7 * 8 = 56

• 10 years agoHelpfull: Yes(0) No(7)
• answer will be 54,54 . because difference between 2 and 12 is 10 then between 12 and 30 is 18. so goin by the difference values next differenc would be of 24 (10+8+6). so 30 + 24 = 54.
