ROR Each Loop Display odd index key entries only

I am working with a dataset which I would like only for the odd number index key entries to be displayed with my each loop in the view file. Right now it works and I get everything.

Here is my controller.rb:

  def index
#Wunderground Controller for API Requests
@wundergroundMap = HTTParty.get('http://api.wunderground.com/api/MySecretAPIKey/satellite/q/CA/Laguna_Beach.json')
@wuMultiDay = @wundergroundForecast['forecast']['txt_forecast']['forecastday']

Here is my view file and loop:

 <% @wuMultiDay.each do |wu| %>
    <div style="width:200px; height: 400px; float: left; border:1px solid; display:inline-block;">

        <h6> Period <%= wu['period'] %></h6>
        <h3 style="text-align:center;"> <%= wu['title'] %></h3>
        <p style="text-align:justify;"><strong>Conditions:</strong><br> <%= wu['fcttext'] %></p>

<% end %>
