If pth,qth,rth terms on an ap are in GP find the common ratio. If pth,qth,rth terms on an ap are in GP find the common ratio.
Dear student Let first term of the AP = a and common difference = d pth of an AP= a+(p−1)d qth of an AP= a+(q−1)d rth of an AP= a+(r−1)d are in G.P Let first term of the GP be x and common ratio be y then a+(p−1)d=x........(i) a+(q−1)d =xy........(ii) a+(r−1)d=xy² ........(iii) Subtract (i) from (ii) and get (q−1)d −(p−1)d=xy−x →(q−p)d=xy−x......(iv) Subtract (ii) from (iii) and get (p−1)d −(r−1)d=xy²−xy =y(xy−x) →(q−r)d=y(xy−x) .....(v) divide (v) by (iv) and get (q−r)/(p−q)= y
