1,7,8,49,50,56,57,343,344,350,351,399,400

• i think some values are missing in the series it should be:
  1,7,8,49,50,56,57,343,344,350,351,393,394,399,400 and the solution is:
  1*7=7,7+1=8
  7*7=49,49+1=50,8*7=56,56+1=57
  49*7=343,343+1=344,50*7=350,350+1=351,56*7=392,392+1=393,57*7=399,399+1=400
  so next will be 343*7=2401(Ans)

  there is a mistake in this series.
  the correct serious should be
  1,7,8,49,50,56,57,343,344,350,351,392,393,399,400

• is ans 406?????
• 10 years agoHelpfull: Yes(2) No(17)
• 400*6=2400
  next no. = 2400+1=2401
• 10 years agoHelpfull: Yes(2) No(2)
• 406 as the series is like, +1,+6,+1,*6+1...therefore 400+6=406
• 10 years agoHelpfull: Yes(2) No(3)
• ans. is after 400 we hav to perform(n+7) so 399+7=406...
• 10 years agoHelpfull: Yes(0) No(9)
• 400+1=401
  not sure
• 10 years agoHelpfull: Yes(0) No(4)
• the series is wrong.the correct series is 1,7,8,49,50,56,57,343,344,350,351,2107
  ...
  a set of 4 numbers should be considered...
  1-7=6
  8-7=1
  8*6+1=49 for next number add +1
  56-50=6
  57-56=1
  57*6+1=343 and so on
