For the following exercises, follow the steps to work with the arithmetic sequence a n = 3 n − 2 using a graphing calculator: • Press [MODE] Select [SEQ] in the fourth line Select [DOT] in the fifth line Press [ENTER] • Press [Y = ] nMin Is the first counting number for the sequence. Set n M i n = 1 u(n) is the pattern for the sequence. Set u ( n ) = 3 n − 2 u ( nMin ) is the first number in the sequence. Set u ( n M i n ) = 1 • Press [2ND] then [WINDOW] to go to TRLSET Set T b l S t a r t = 1 Set Δ T b l = l Set lndpnt: Auto and Depend: Auto • Press [2ND] then [GRAPH] to go to the [TABLE] 62. Use the scroll-down arrow to scroll to n = 50 . What value is given for u ( n )?
