find the next term-
3,15,35,63..

• 1*3 = 3
  3*5 =15
  5*7 =35
  7*9 =63
  9*11=99 .so,ans is 99. all numbers are odd numbers
• 10 years agoHelpfull: Yes(27) No(0)
• 2^2-1=3
  4^2-1=15
  6^2-1=35
  8^2-1=63
  
  so, next no. is (10^2-1) = 99
• 10 years agoHelpfull: Yes(12) No(0)
• Ans: 99.
  Coz int his series odd number multiples are considered. So,
  1*3=3
  3*5=15
  5*7=35
  7*9=63
  9*11=99
• 10 years agoHelpfull: Yes(3) No(0)
• ans:80
  4-1,16-1,36-1,64-1,81-1
• 10 years agoHelpfull: Yes(2) No(6)
• ans:99
  
  3,15,35,63
  
  step:1
  2nd term-1st term
  15-3,35-15,63-35,x-63
  it gives
  12,20,28(2nd term=1st+8) so next one is 36
  so x-63=36
  x=99
• 10 years agoHelpfull: Yes(2) No(0)
• ans- 99
  sol- 1*3,3*5,5*7,7*9,9*11
• 10 years agoHelpfull: Yes(1) No(0)
• ans next no. will be 99 as the series is
  3 the 3*5=15 then 5*7=35 the 7*9=63 then it will be 9*11=99 as both multiples are increasing by 2 in this series

• 99... because the difference between first two numbers is 12 n next two is 20 n next two is 28... every time 8 is added... so, 28+8=36... 36 should be added to 63, hence the answer is 99

• 99
  the addition of 8 in diff betn two digits

• difference between numbers is considered i.e., 15-3=12, 35-15=20, 63-35=28,
  again the difference is taken between them , 20-12=8, 28-20=8,x-28=8, where x=36,
  fifth no=63+36=99
