    let, \( n\) be the number of terms!! given, \( S_n - a = -36 \implies \frac{n (a+l)}{2} - a = -36\) or \( \frac{n (2a+(n-1)d)}{n} - a = -36\) -------- 1 \( S_n - l = 0 \implies \frac{n (a+l)}{2} - l = 0\) or, \frac{n(2a+(n-1)d)}{n} - a - (n-1)d = 0\) -------- 2 <-- also it implies that AP must be And \( a + (5-1)d - (a + (10-1)d = 16 \) ---- 3 3 unknown variables and three equations ... it should be solveable!!
