Google Sheets clearing every other cell with a script

I have a sheet that have formulas on column B at every other Row starting from B3, so it's B3, B5 and up to B101, I have the following script to clear the rest of the sheet except for column B, How can I add to the function to clear every other row from B3 to B101?

function ClearCells() { var sheet = SpreadsheetApp.getActive().getSheetByName('sheetName'); sheet.getRange('C3:T102').clearContent(); sheet.getRange('A3:A102').clearContent(); }
