+## Example: `seq` with `range` and `after`
+
+You can use `seq` in combination with `range` and `after`. The following will return 19 elements:
+
+```golang
+{{ range after 1 (seq 20)}}
+{{ end }}
+```
+
+However, when ranging with an index, the following may be less confusing in that `$indexStartingAt1` and `$num` will return `1,2,3 ... 20`:
+
+```golang
+{{ range $index, $num := (seq 20) }}
+$indexStartingAt1 := (add $index 1)
+{{ end }}
+```
