I have a large raster layer that has aridity values assigned to each pixel. I also have latitude and longitude data of some locations in USA. I would like to know the pixel value according to my latitude and longitude locations . I first clipped the raster to my area of interest (USA) in Arcmap the I converted my clipped raster in to a .tif file. I don't know how to extract the pixel values according to the locations that I have. I tried a few things but it either doesn't work or I don't have the license (such as for extract). 

Thank You for your help^^

I have attached an image of what I have.

Extract Values to Points or its brethren Extract MultiValues to Points IF you have the spatial analyst extension

Hello Dan thank you for your reply^^
I unfortunately don't have the spatial analyst extension, is there a way around this?

There is... but it requires programming in python and numpy... sorry... so short of  the info tool, you are a bit stuck

Here is a document that could get you started, but you will have to program using Python: https://community.esri.com/docs/DOC-2954
