With your teacher: The first term of a arithmetic sequence is 14 . The \( 7^{\text {th }} \) term is 50 . Find: (a) The common difference ' \( d \) '. (b) The rule for the sequence. The \( 6^{\text {th }} \) term of an arithmetic sequence is 123 . The \( 11^{\text {th }} \) term is 98 . Find; (a) The common difference ' \( d \) ' and first term ' \( a \) '. The rule for the sequence. (b) (c) \( 16^{\text {th }} \) term.
