70, 54, 45, 41……. What is the next number in the given series?

• ans is 40.70-4^2=54,54-9=45,45-4=41,41-1=40

• it is very simple question of series
  
  ans=40
  70-40=16=square of 4
  54-45=9=square of 3
  45-41=4=square of 2
  so next no will be square of 1
  41-1=40
  
• 11 years agoHelpfull: Yes(28) No(2)
• answer is 40.
  41+2^2=45
  45+3^2=54
  54+4^2=70

  ans=40
  70-54=16=square of 4
  54-45=9=square of 3

• 70, 54, 45, 41
  so the next no. will be 40in the series
  because 70-54=16=4^2
  54-45=9=3^2
  45-41=4=2^2
  41-40=1=1^1

• Ans-40,
  first 70-16=54 which means 4^2 then
  54-45=9 which means 3^2 then
  45-41=4 which means 2^2 then 2 after come 1 so
  41-1=40 which means 1^1 so answer got...--->
  40

• answer is 40
  54 = 70 - 4^2
  45 = 54 - 3^2
  41 = 45 - 2^2
  40 = 41 - 1^2

• ans is 40 because
  40+1^2=41
  41+2^2=45
  45+3^2=54
  54+4^2=70

• 40
  because difference is square of no 4,3,2 then 1

• 70-54=4^2;
  54-45=3^2;
  45-41=2^2;
  41-40=1^2
  => ans is 1

• 40. Because consecutive square of no.starting from 4 to 1

• The answer is: 40
  It seems the difference between each by the square of 4, 3 and 2 respectively (moving from left-to-right) i.e 70 and 54 has a difference of 16 which is square of 4 and so on.
  Thus final result is square at 1 i.e 40.

• next number is 40
  70-4^2=54,
  54-3^2=45,
  45-2^2=41,
  41-1^2=40
• 5 years agoHelpfull: Yes(0) No(0)
• 70-54=16
  54-45=9
  45-41=4
  41-x=1 ==>x=40

• 70-54=16.....16 is square of 4
  54-45=9 ......9 is square of 3
  45-41=4 .......4 is square of 2
  41-40=1 ......now 1 is square of itself that is 1

• 40 cause each time it is reduced by the square of n and n=4 at first then it is 3 and so on.

• consecutive differnce between two nos are 16,9,4 i.e 4^2,3^2,2^2 therefor difference between 41 and missing no is 1^1 i.e 41-14=1^1 ,40 is the answer

• Ans: 40
  Explanation: 70-54=16=4^2
  54-45=9=3^2
  45-41=4=2^2
  Therefore, the next no is such that it is maintaining a difference of 1^2 with its preceding number.
  Hence,41-1^2=40.

• Given series is 70,54,45,41........
  70-54=16 ---->4^2
  54-45=9 ---->3^2
  45-41=4 ---->2^2
  so, 41-1^2=40
• 4 years agoHelpfull: Yes(0) No(0)
• 70-(4^2)=54
  54-(3^2)=45
  45-(2^2)=41
  41-(1^2)=40
  Therefore, answer is 40

• answer is 40...
  the differemce between the series is square of 2,3,4
  then the last series is 40

• 40
  ans=40
  70-40=16:square of 4
  54-45=9:square of 3
  45-41=4:square of 2
  40-41=1:SQUARE OF 1
  41-1=40

• Answer is 40 . that can be understandable..
  but what about 38 ???? It also can be answer if focus on the difference of number .
  like: 16,9,4.... so difference b/w them be like: 7,5.. so next can be 3 and according to the difference next could be "38" also.
