+## Missing second '(' to start arithmetic for ((;;)) loop
+
+### Problematic code:
+
+```sh
+for (i=0; i<10; i++))
+do
+  echo $i
+done
+```
+
+### Correct code:
+
+```sh
+for ((i=0; i<10; i++))
+do
+  echo $i
+done
+```
+### Rationale:
+
+ShellCheck found an arithmetic `for ((;;))` expression where either the `((` or the `))` did not come as a pair. Make sure to use `(( ))` and not `( )`. 
+
+### Exceptions:
+
+None.
