Let S1 be the sum of the first n terms of the A.P. 8,12,16………… and let S2 be the sum of the first n terms of the A.P 17,19,21…………, assume n≠0, then S1=S2 for:
no value of n
one value of n
two values of n
more than 2 values of n
n2[2.8+(n−1)4]=n2[2.17+(n−1)2]n[8+2(n−1)]=n(17+n−1)2n2+6n=n2+16nn2−10n=0n=0 (impossible) n=10
