1/56, 1/36, 1/29, 1/16, ?

• 1/(8*7)=>1/56
  ---------------1/(6*6)=>1/36
  1/(6*5)-1=>1/30-1=>1/29
  ---------------1/(4*4)=> 1/16
  1/(4*3)-2->1/10-2 => 1/10

• 1/((7*7)+7)=1/56
  1/(6*6)=1/36
  1/((5*5)+4))=1/29
  1/(4*4)=1/16
  1/((3*3)+1)=1/10

• Ans should be 1/10
  because series like 1/(7^2)+7,1/6^2,1/(5^2)+4,1/4^2, so next term will be 1/(3^2)+1=1/10

• i think its 1/5
  cz diff btwn 1st two no's denomenator is 20 then following diff is 17,13.
  so the next no will have 11 diff.

• 56-36=20 , 36-29=7, 29-16=13
  20-7=13, 7-13=-6
  => 16-(-6)=22
  
  Ans. 22

• 56-20=36,36-7=29,29-13=16
  20-13=7
  7-(-6)=13
  hence ans is 1/16-(-6) =1/22
