To find the \( r^{th} \) term from the end in the expansion of \( (x + a)^n \), we can follow these steps: ### Step 1: Understand the formula for the \( r^{th} \) term from the end The \( r^{th} \) term from the end in the expansion of \( (x + a)^n \) can be expressed in terms of the \( (n - r + 1)^{th} \) term from the beginning. The relationship is given by: \[ T_{r} = T_{n - r + 1} \] ...
