IQueryable for Anonymous Types

I use EntityFramework, I'm querying and returning partial data using Anonymous Types. Currently I'm using IQueryable<dynamic>, it works, but I would like to know if this is the proper way to do it or if there is some other returning datatype that I'm not aware of.

public IQueryable<dynamic> FindUpcomingEventsCustom(int daysFuture)
{
    DateTime dateTimeNow = DateTime.UtcNow;
    DateTime dateTimeFuture = dateTimeNow.AddDays(daysFuture);
    return db.EventCustoms.Where(x => x.DataTimeStart > dateTimeNow & x.DataTimeStart <= dateTimeFuture)
        .Select(y => new { y.EventId, y.EventTitle, y.DataTimeStart});
}
