If the p of term Ap is q and q term is p prove that it\'s n term is (p+q-n) |
| Answer» ap=a+[p-1]d=q-----eqn no. 1aq=a+[q-1]d=p-----eqn no. 2Subract 2 from 1....we getd=q-p/p-qd=-1 Then from eqn 1....a=q+p-1......Then an=a+[n-1] dPut value of a and d in above eqn Then we get an=q+p-n.... Which is equals to... P+q-n...Hence proved...... | |
