What will be the 10th term in series 3,0,-3,-6 ?
a) -21
b) -24
c) -27

• a=3, d= -3, n=10
  we know ,n'th term = a+(n-1)d
  =3+(10-1)*(-3)
  =3-27 = -24

• 3,0,-3,-6,-9,-12,-15,-18,-21,-23 it will increase by 3 ans:-23
• 8 years agoHelpfull: Yes(2) No(32)
• it is ap where a=3 d=(-3) n=10 so nth term is=a+(n-1)d
  
  so 10th term=3+(10-1)(-3)=24
• 8 years agoHelpfull: Yes(2) No(3)
• -24
  because in this term a=3 ,diffirence d=-3 and n=1
  a+(n-1).d=3+(10-1)*-3
  3+9*-3=3-27=-24

• b) -24 is the right answer
• 8 years agoHelpfull: Yes(1) No(0)
• tn=a+(n-1)d
  -24
• 8 years agoHelpfull: Yes(1) No(1)
• by the formula an = a1+(n-1)*d
  nth term = 10
  a1 = first term = 3
  difference (d) = 0-3= -3
  substituting in the formula a10 = 3+(10-1)*(-3)
  ANSWER: -24

• this term are in AP
  L=a+(n-1)*d
  l=3+(10-1)*(-3)=-24
• 8 years agoHelpfull: Yes(1) No(0)
• decreasing by 3,and the 10th term is -24
• 8 years agoHelpfull: Yes(1) No(0)
• 3,0,-3,-6,-9,- 12, -15,-18,-21,-24 the tenth term is -24
• 8 years agoHelpfull: Yes(0) No(0)
• 3+(9-1)*-3
• 8 years agoHelpfull: Yes(0) No(0)
• it is in A.P ,SO IT WILL BE
  b) -24
• 8 years agoHelpfull: Yes(0) No(1)
• a+(n-1)d=3+(10-1)*-3
  
• 8 years agoHelpfull: Yes(0) No(0)
• t10 = a+(n-1)d
  a = 3, d = -3
  t10 = 3+(10-1)(-3)
  t10 =-24
• 8 years agoHelpfull: Yes(0) No(0)
• It is in form of A.P
  Where a=3 d=-3
  we know that nth term=a+(n-1)d
  3+(10-1)(-3)=-24
• 8 years agoHelpfull: Yes(0) No(0)
• 3,0,-3,-6,-9,-12,-15,-18,-21,-24
  Hence 10th term in this series is -24
• 8 years agoHelpfull: Yes(0) No(0)
• -24
  a+(n-1)d
• 8 years agoHelpfull: Yes(0) No(0)
• 3 0 -3 -6 -9 -12 -15 -18 -21 -24
  10th element is -24
• 8 years agoHelpfull: Yes(0) No(0)
• Ans -24. since the given series in A.P
  Use formula a+(n-1)d to find the 10th term.
• 8 years agoHelpfull: Yes(0) No(0)
• its in AP. so,
  a=3,d=-3 & to find t10=?
  t10=a+(n-1)d
  =3+(9)*-3
  =-24
• 8 years agoHelpfull: Yes(0) No(0)
• In ths serious it decreases by 3
  Hence it is -24
  3 0 -3 -6 -9 -12 -15 -18 -21 -24
  
• 8 years agoHelpfull: Yes(0) No(0)
• it is in AP so using its formula for finding the 10th term a+(n-1)d here a=3 d=-3 n=10 so 3+(9)*-3=-24
• 8 years agoHelpfull: Yes(0) No(0)
• 3,0,-3,-6,-9,-12,-15,-18,-21,24
• 8 years agoHelpfull: Yes(0) No(0)
• -24
  assume a number line a count to the left from 3 taking 3 as common difference
  
• 8 years agoHelpfull: Yes(0) No(0)
• difference is 3 ans:-24
• 8 years agoHelpfull: Yes(0) No(0)
• a=3
  d=-1
  t10=a+9d
  =>3+9*-3=-24
• 8 years agoHelpfull: Yes(0) No(0)
• -24
  it is AP series a=3 d=-3 and n=10
  so the ans is -24
• 7 years agoHelpfull: Yes(0) No(0)
• Ans B.-24
• 7 years agoHelpfull: Yes(0) No(0)
• 3,0,-3,-6,-9,-12,-15,-18,-21,-24
• 7 years agoHelpfull: Yes(0) No(0)
• don't confuse
  t10=a+9d, where a is 3 & d is -3
  so
  t10=3+9(-3)
  t10=-24
