  1. Solution is 54325
    consider f(0)=5
    the equation is f(n)=10^(n-1)*n+f(n-1)
    the equation will satisfies form n>0
    f(1)=10^0*1+5=5
    f(2)=10^1*2+5=25
    f(3)=10^2*3+25=325
    f(4)=10^3*4+325=4325
    f(5)=10^4*5+4325=54325

    1. f(1)=10^0*1+5=5 is incorrect

      f(1)=10^0*1+5=6 because anything raise to the power zero equals one not zero. so 1*1+ 5 =1+5 = 6

    2. Typo:

      "raise" should be "raised"
