what is the next number of following series
1,5,5,3,10,10,5,6,...

• ans is 15
  1^2=1
  1+2^2=5
  5+3^2=14=>1+4=5
  14+4^2=30=>3+0=3
  30+5^2=55=>5+5=10
  55+36=>91=>9+1=10
  91+49=140=>5
  14)+64=204=6
  so
  
  204+81=285=>15

• ans:6
  
  1^2 = 1
  1 + 2^2 = 5
  5 + 3^2 = 5+9 = 14 = 1+4 = 5
  5 + 4^2 = 5+16= 21 = 2+1 = 3
  3 + 5^2 = 3+25= 28 = 2+8 = 10
  10+ 6^2 =10+36= 46 = 4+6 = 10
  10+ 7^2 =10+49= 59 = 5+9 = 14 = 1+4 = 5
  5 + 8^2 = 5+64= 69 = 6+9 = 15 = 1+5 = 6
  6 + 9^2 = 6+81= 87 = 8+7 = 15 = 1+5 = 6
  
  When the number is greater then 10, the digits are added to get the ans.
