Importance of General Terms in GP and AP
Once you complete the introduction, get some of the brief information about the geometry progression and its real-life usefulness. There are questions given in exercise 8.2 based on daily life experience. You need to give proper time to passage given in NCERT for general term of G.P. This says that if G.P with first positive term a and common ratio r, the second term is obtained by multiplying a by r. This provides us the result a₃ = a₂r = ar², and more.
