SEQUENCE & SERIES II

Content

  • Nth term of a G.P
  • Geometric Mean
  • Sum of n terms of a G.P
  • Sum to infinity of a G.P

 

Nth term of a G.P

A Geometric Progression is a sequence generated by multiplying or dividing a preceding term by a constant number to get a term. This constant number is called the common ratio designated by the letter r.

Evaluation

(1)      Find T9 of the G.P 5, 2½, 1¼, 5/8 …………..

(2)      If 3, p, q, 24 are consecutive terms of an exponential sequence, find the values of p and q.
