the sum of 5 consecutive whole numbers is 2005. what is the sum of all the digits of these 5 numbers

  • Math - ,

    so you have,

    (n-2)+(n-1)+n+(n+1)+(n+2)=2005
    5n=2005
    n=401
    nos are,
    399,400,401,402,403

  • Math - ,

    n-4 + n-2 + n + n+2 + n+4 = 2005

    5 n = 2005

    n = 401
    so the list

    397
    399
    401
    403
    405
    so
    2*3 + 3*4 + 2*9 + 25
    = 61

  • Sorry - ,

    I misread it, thought it said ODD numbers
