1, 4, 2, 8, 6, 24, 22, 88, ___

• Ans. 86
  Explanation:
  
  The series is
  1
  1*4=4
  4-2=2
  2*4=8
  8-2=6
  6*4=24
  24-2=22
  22*4=88
  88-2=86
  86*4=344
  i.e alternatively subtract 2 and then multiply by 4 to get other terms.

• consider pairs as (1,4),(2,8),(6,24),(22,88).in each pair,(2nd digit-2)= first digit in next pair.so,88-2=86.

• first of all even terms are multiple of 4 of corresponding predecessor odd terms.ok after that we concentrate on only ODD term so, 1*4-2=2(3rd term)
  2*4-2=6(5th),6*4-2=22(7th).....similarly
  22*4-2=86.............so Ans is 86

• 86.
  alternate
  1+1^2=2
  2+2^2=6
  6+4^2=22
  22+8^2=86

• answer :: 86,344
  sol:: 1,4,2,8,24,22,88,.....
  in series every "even term" is multiple of 4 of it earlier term.
  and every "odd term" get reduce by 2 from it earlier term.
  so series will be
  1,4,2,8,6,24,22,88,86,344.....

• first term is multiplied by 4 then 2 is substracted
  so the next term will be 86

• 86.every number is multiplied by 4 and subtracted by 2.

• 86
  4-2=2 8-2=6 24-22=2 88-2=86
• 12 years agoHelpfull: Yes(0) No(0)
• (1,4),(2,8),(6,24),(22,88)
  1
  1*4=4
  2
  4*2=8
  (1*4)+2=6
  6*4=24
  (8*2)+6=22
  22*4=88
  (24*6)+22=166
  
  So ans is 166
