Define #N by the formula #N=.5(N)+1. Calculate

#(#(#50)).

#50=26

#(26)=14
#(14)=8

To calculate #(#(#50)), we need to substitute the value of 50 into the formula recursively.

Let's start with the innermost parentheses, #50. We substitute 50 into the formula #N = 0.5(N) + 1:

#50 = 0.5(50) + 1
= 25 + 1
= 26

Now we have #26. Again, we substitute 26 into the formula:

#26 = 0.5(26) + 1
= 13 + 1
= 14

Finally, we have #14. Substituting again:

#14 = 0.5(14) + 1
= 7 + 1
= 8

Therefore, #(#(#50)) is equal to 8.
