Answer» Heya mate..... ✨✨❤ Here's ur answer : »» Let a and d RESPECTIVELY be the first term and the COMMON difference of an A.P. According to the given conditions, a + (m-N)d = n ------(1) a + (n-1)d = m ------(2) On solving eqn (1) & (2) , we get, » d = -1 ; a = m+n-1 Therefore, »» rth term = a+(r-1)d .°. » rth term = (m+n-1) - (r-1) .°. » rth term = m+n-r ,, »» Hope it helps !!! «« Plz! Mark it as BRAINLIEST * and don't forget to follow me .....✌✨
