a) If two of the terms of an arithmetic progression \( s \) are: \[ s_{1}=6 \text { and } s_{3}=9 \] find the value of the difference, \( d \). b) Find the general term of the progression, \( s_{n} \)

Find the general term of the following arithmetic sequence then find the indicated term of the sequence. \( 4,13,22,31, \ldots ; a_{12} \) The general term of the given arithmetic sequence, \( a_{n}=\square \). (Simplify your answer.) The indicated term of the sequence, \( a_{12}=\square \). (Simplify your answer.)
