```:Seq
```

The graphing mode becomes Sequential graphing mode. In this mode, the parameter is n instead of X. Also, equations can call themselves to create such commands as $u(n)=u(n-1)+2$ since the mode includes variables to set the first value of an equation.

• MODE
• SEQ

ExampleEdit

```:Seq
:"1/(u(n-1)+1)"→u
:{1}→u(nMin)
:DispGraph
```

This displays a sequential function, using the sequential abilities of the equation.
