which term of the series 27,24,21,18,15,....is the first neagtive term
option
1) 9
2) 7
3) 16
4) 11
5) 15
6) 14
7) 10
8) 13
9) 12
10) 8

• 1st -ve term of the series is (-3).
  from the A.P series formula,
  tn=a+(n-1)d
  put tn=-3; a=27;d=-3
  the solution is n=11(ans.)

• 3
  Becoz 27-3=24
  24-3=21
  21-3=18
  18-3=15
  15-3=12

• These numbers are in the series 27,24,21,18,15,12,9,6,3,1,-1......... the first negative term starts in the place of 10
• 7 years agoHelpfull: Yes(4) No(1)
• 11th term is the first -ve term which is -3.
  
  
• 7 years agoHelpfull: Yes(4) No(0)
• 3*9=27
  3*88=24
  .
  .
  .
  3*5=15
  so 3*4=12
  so 12 is the answer

• 9 . difference is 3
• 8 years agoHelpfull: Yes(2) No(1)
• Any idea when aspire for the selected candidates(2nd march) is gonna start and when we will get the joining letter...???
• 8 years agoHelpfull: Yes(1) No(2)
• Option 9. Since 9*3=27,8*3=24,•••4*3=12
• 7 years agoHelpfull: Yes(1) No(1)
• 28-3=25
  25=25-3=21
  Like that
  15 -3=12
  Finally answer is 12
• 7 years agoHelpfull: Yes(1) No(1)
• it is an AP or you can say a table of 3 but in reverse order so if you see there are 10 terms till the number gets 0 and after that we get negative terms
  So First negative will be 11 term
• 7 years agoHelpfull: Yes(1) No(0)
• a=25,d=-3 and find n=?
  let nth term=0
  then
  0=a+(n-1)d
  0=25+(n-)-3
  we have to solve and we get value of n is10.
  10th term is 0 and 1st -ve value in 10+1 term.
  so Ans is 11.

• Here all the numbers are in difference of 3, but 16 is first number which is not.
• 8 years agoHelpfull: Yes(0) No(2)
• 11. every time there is a decrement of 3.in this logic it should be 11
• 8 years agoHelpfull: Yes(0) No(1)
• 12,9 multipule with 3
• 8 years agoHelpfull: Yes(0) No(0)
• 27-24=3 , 18-15=3
• 8 years agoHelpfull: Yes(0) No(0)
• 12
  as all numbers are decreasing multiple of 3
• 8 years agoHelpfull: Yes(0) No(0)
• 11,given series is in ap with d = -3 so first term is-3
• 8 years agoHelpfull: Yes(0) No(0)
• 12
  every time he can minuses 3
• 7 years agoHelpfull: Yes(0) No(0)
• 9) 12
  18-6=12
  
• 7 years agoHelpfull: Yes(0) No(1)
• we should do -3 for evry term so at last we get 12
  
• 7 years agoHelpfull: Yes(0) No(1)
• 12+3=15
  15+3=18......
  24+4=27
• 7 years agoHelpfull: Yes(0) No(0)
• 11
  as the sries is the table of 3 & 27,26,24,21,18,15,12,9,6,3,0,-1
• 7 years agoHelpfull: Yes(0) No(0)
• ans is 12
  3*9,3*8,3*7,3*6,3*5,3*4
• 7 years agoHelpfull: Yes(0) No(0)
• i think .. in this series the difference is 3 and the 1st -ve number is -3... 27,24,21,18,15,12,9,6,3,0,-3 that is the series and -3 is the 11th term so the ans is 4) 11
• 7 years agoHelpfull: Yes(0) No(0)
• -3=27+(n-1)(-3)
  so n=11
• 7 years agoHelpfull: Yes(0) No(0)
• ans is 12.
  because defference is 3
• 7 years agoHelpfull: Yes(0) No(0)
• 12 BASED ON SERIES 6 DIFFERENCE IS THERE
• 7 years agoHelpfull: Yes(0) No(0)
• Here all are factors of 3 only then here missing one is 12
• 7 years agoHelpfull: Yes(0) No(0)
• answer is 12, because the series is 3 multiples in descending order
