What will be in the next series
1, 7, 8, 49, 56, 57, 343, ...

• answer is 392
  1 is multiplied by 7 then added 1 to it,so we get 8
  now take 7 and multiply with 7 we get 49,repeat same with 8 we get 56.
  when we are done multiplying with previousely generated nos add 1 to last generated no. so we get 57.
  now start with 49 and multiply with 7 we get 343 then multiply 56 by 7 we get 392.

• 1
  1*7 =7
  1*7+1 =8
  7*7 =49
  7*7+1 =50
  8*7 =56
  8*7+1 =57
  49*7 =343
  49*7+1=344
  
  ANS: 344

• Ans is 350 because 1,7,7+1=8,8×6+1=49,49+7=56,56+1=57,57×6+1
  =343,343+7=350

• next two numbers will be 350 & 351
• 9 years agoHelpfull: Yes(2) No(0)
• 344 is the answer
• 9 years agoHelpfull: Yes(1) No(0)
• 1*7=7
  7+1=8
  7*7=49
  8*7=56
  56+1=57
  49*7=343
  57*7=399
  here 1,7,7 is being repeated... here first is addition(7+1=8) then the square of 7(7*7=49) and then the addition term is multiplied with 7(8*7=56)
  similarly(56+1=57) then (7*7*7=343) and then (57*7=399)

• The answer is 392 we can see that 1,7 ,8 8=7+1,also 49=7*7 and 56=7*8 and 57=7*8+1,following this logic number after 343 shud be 392

• Ans-512.because 8 cude is this

• the series is given as successive digits repeats after 1st 4th 7th ....
  relation between 1&7 is 6*1+1
  7 and 8 successive
  relation between 8 &49 is 6*8+1
  and 56 will b given as 7*8=56
  56 ,57 successive
  then 57*6+1=343 successive no. is 344

• 1*1=1
  1*7 =7
  1*7+1 =8
  7*7 =49
  8*7=56
  8*7+1=57
  49*7 =343
  56*7=392
  so answer is 392
  first two multiplication than one addition and so on....
