Who Am I? Number Puzzle

I am a number.  I am the sum of the measures of the interior angles of a triangle, divided by the number of sides in a dodecagon, multiplied by the most frequently occurring digit in the first 5 numbers in the sequence, 1, 4, 16, 64, 256..., and less the median of those same 5 numbers.  What number am I?

Well, the number is ___74_______

Here is my work:

 The sum of the interior angles in a triangle is always 180 degrees.

 Then I divided 180 by 12 which resulted in 15. 

After that, I continued on the sequence until 5 numbers (1, 4, 16, 64, 256) and found out that 6 is the most common digit. So I multiplied 6 to 15 which resulted in 90. 

Finally, I subtracted 90 by the median of the 5 numbers (16) and the final result is 74!

You could also set up an formula by using the given information.

Let x represent the mystery number:

x= (180/12)6 - 16

x=74
