Arithmetic Sequences · Exercise 67

Follow the steps to work with the arithmetic sequence $a_n=3n-2$ using a graphing calculator:

• Press [MODE]
• Select SEQ in the fourth line
• Select DOT in the fifth line
• Press [ENTER]
• Press [Y=]
• $n\text{Min}$ is the first counting number for the sequence. Set $n\text{Min}=1$
• $u\left(n\right)$ is the pattern for the sequence. Set $u\left(n\right)=3n-2$
• $u(n\text{Min})$ is the first number in the sequence. Set $u(n\text{Min})=1$
• Press [2ND] then [WINDOW] to go to TBLSET
• Set $\text{TblStart}=1$
• Set $\Delta \text{Tbl}=1$
• Set Indpnt: Auto and Depend: Auto
• Press [2ND] then [GRAPH] to go to the TABLE

Use the scroll-down arrow to scroll to $n=50.$ What value is given for $u\left(n\right)?$

Its source prints no answer for this problem, so there's nothing to check against.
