i think there is lots of solution but one of the solution maybe: 47,49,51,53,57

I think that solution may be the only one given the restriction of all numbers being odd. If you picked a higher number the average would no longer be 53.

Only one solution; the one given by Johnny.

(x + 45 + 69) / 7 = 53

x = 257 = the sum of the 5 missing numbers.
