If
17 + 3 = 31;
23 + 5 = 38;
32 + 9 = 55
then

65 expalination 17+(3×2)+1+7=31,23+(5×2)+2+3=38,32+(9×2)+3+2=55

17+3+(1+7+3)= 31
23+5+(2+3+5)= 38
32+9+(3+2+9)= 55
So...
38+8=....?
38+8+(3+8+8)= 65

I think since 17+3=31 , 23+5=38...32+9=55... so 38+8= 38+5+3=??(need to be calculated)
i.e 38+5=43 increment by 10 so 38+5=53-----------eqn.1
similarly , 38+3=41 increment by 11 so 38+3=52--------------eqn2

from eqn1 and eqn2,,,we get,,,
38+5+3= 53+52= 105...
