For a positive integer n , let `a(n) = 1+ 1/2 + 1/3 +…+ 1/(2^(n)-1)` : Then

For a positive integer n let a(n)=1+1/2+1/3+1/4+….+1/ ((2^n)-1) Then

For a positive integer n let a(n)=1+1/2+1/3+1/4+.......+1/((2^n)-1) then

For a positive integer n let a(n)=1+1/2+1/3+1/4+.....+1/((2^n)-1)dot Then a(200)lt=100 b. a(200) > 100 c. a(200)lt=100 d. a(200)lt=100

For a positive integer n let a(n)=1+1/2+1/3+1/4+1/((2^n)-1)dot Then a(100)lt=100 b. a(100)dot> 100 c. a(200)lt=100 d. a(200)lt=100

For a positive integer n, let a_(n) = 1+( 1)/( 2) +( 1)/( 3) + ( 1)/( 4) + "......." + ( 1)/(( 2^(n) - 1)) . Then :

For a positive integer n let a(n)=1+1/2+1/3+1/4+.....+1/((2^n)-1)dot Then

For a positive integer n, let a(n)=1+(1)/(2)+(1)/(3)+(1)/(4)+ . . .+(1)/(2^(n)-1) Then:

For a positive integer (n gt 1) , Let a (n) = 1+ (1)/(2) + (1)/(3) + (1)/(4) ….... + (1)/( (2^(n) )-1) Then

For a positive integer n let a(n)=1+(1)/(2)+(1)/(3)+(1)/(4)cdots+(1)/((2^(n))-1). Then a(100) 100c.a(200)<=100d.a(200)<=100
