Highlight cells if found

I have a datagrid that outputs 90 rows after being bound to a datatable. The rows values are the 1-90 ascending.

What I want to achieve:

If the number is found in an array/range/list of numbers then highlight it green.

I have managed to get it to highlight the cell based on 1 value, but I want to highlight several cells if they are found in the range.

<DataGrid Name="grid" ItemsSource="{Binding}" Height="300" Width="900"
          AutoGenerateColumns="False"
          VerticalScrollBarVisibility="Disabled" HorizontalAlignment="Center" VerticalAlignment="Top" RowHeight="40">
            <DataGrid.Resources>
                <Style x:Key="BackgroundColourStyle" TargetType="{x:Type TextBlock}">
                    <Style.Triggers>
                        <Trigger Property="Text" Value="1">
                            <Setter Property="Background" Value="LightGreen" />
                        </Trigger>
                    </Style.Triggers>
                </Style>
            </DataGrid.Resources>
            <DataGrid.Columns>
                <DataGridTextColumn Binding="{Binding Path=Number}" 
            ElementStyle="{StaticResource BackgroundColourStyle}" MinWidth="40">
                </DataGridTextColumn>
            </DataGrid.Columns>

            <DataGrid.ItemsPanel>
                <ItemsPanelTemplate>                    
                    <WrapPanel Orientation="Vertical" />
                </ItemsPanelTemplate>
            </DataGrid.ItemsPanel>
        </DataGrid>

you can see I have a trigger property of the value 1. This works fine, but as above, how do I change this so if a cell is in the range set in c# in backend then highlight it green.

binding to datatable:

calledGrid.DataContext = calledNumbers.DefaultView;

The actual making of the datatable:

DataSet dataSet = new DataSet("myDS");
            this.bingoCalls(dataSet);
            DataTable numbersTable = new DataTable("Numbers");
            numbersTable.Columns.Add("Number", typeof(Int32));

            for (int i = 1; i < 91; i++)
            {
                numbersTable.Rows.Add(i);
            }
            dataSet.Tables.Add(numbersTable);
