The mean of 1,2,2^2,2^3.....2^31 lies in between
A)2^24 to 2^25
B)2^25 to 2^26
C)2^26 to 2^27
D)2^29 to 2^30

• C)2^26 to 2^27
  
  Mean = sum of n numbers / n
  
  Numbers if terms = n = 32
  Sum = 1 + 2 + 2^2 + ... + 2^31 = 2^32 - 1
  
  => Mean = (2^32 - 1)/32 = 2^27 - (1/32)
  => Mean lies b/w 2^26 and 2^27 i.e opt c

• 1,2,2^2,2^3.......2^31=2^32
  taking average of 2^32 it is 2^32/32=2^27-1/2^5
  so the range is from 2^26 to 2^27
