- 1
- −1
- 0
- sec²2θ
If a and d are the first term and the common difference of the A.P respectively, then the nth term of corresponding H.P is
- an = a+(n-1)d
- an = 1/a+(n-1)d
- an = a/1+(n-1)d
- an = a/a+(n-1)d
If n is the total number of geometric mean between a and b than the nth geometric mean between a and b is
- a(b/a)n/n+1
- a(b/a)m/n+1
- b(a/b)m/n+1
- ab
