In an A.P; the common difference is −2 and the largest term  exceeds the middle term by 58.  Find the smallest term of the A.P.

Let m is a middle term  m+58 is the largest term.  ∴ m−58 is the smallest term.  AP  will be:  m+58,m+56,...,m,m−2,...,m−58  The smallest term=m−58         m: Middle term
$$\mathrm{Let}\:\mathrm{m}\:\mathrm{is}\:\mathrm{a}\:\mathrm{middle}\:\mathrm{term} \\ $$$$\mathrm{m}+\mathrm{58}\:\mathrm{is}\:\mathrm{the}\:\mathrm{largest}\:\mathrm{term}. \\ $$$$\therefore\:\mathrm{m}−\mathrm{58}\:\mathrm{is}\:\mathrm{the}\:\mathrm{smallest}\:\mathrm{term}. \\ $$$$\mathrm{AP}\:\:\mathrm{will}\:\mathrm{be}: \\ $$$$\mathrm{m}+\mathrm{58},\mathrm{m}+\mathrm{56},…,\mathrm{m},\mathrm{m}−\mathrm{2},…,\mathrm{m}−\mathrm{58} \\ $$$$\mathrm{The}\:\mathrm{smallest}\:\mathrm{term}=\mathrm{m}−\mathrm{58} \\ $$$$\:\:\:\:\:\:\:\mathrm{m}:\:\mathrm{Middle}\:\mathrm{term} \\ $$
