Hi Edward,
Telerik UI for ASP.NET AJAX does not require you to manually add or target a specific jQuery version in order for the controls to work. The reason you do not see a jQuery requirement listed next to the .NET 4.6.2+ requirement is that the suite includes its own jQuery build.
For ASP.NET Web Forms projects, the controls are designed around the ASP.NET AJAX (MS AJAX) framework, which is compatible with jQuery 1.x. Because of that, Telerik UI for ASP.NET AJAX ships with an embedded custom jQuery 1.12.4 build inside Telerik.Web.UI.
This embedded jQuery version is patched/backported to address known security vulnerabilities and is used by the controls automatically for their internal client-side functionality.

Can I use a newer jQuery version (2.x/3.x) in my application?
Yes - your page can load a newer jQuery version for your own scripts. However:
- By default, Telerik controls will continue using their embedded patched jQuery 1.12.4, even if a newer jQuery is present on the page.
- If you explicitly configure the controls to use the jQuery instance from the page (instead of the embedded one), then you will need to test compatibility with your chosen jQuery version, because WebForms/MS AJAX + the control client-side scripts were designed around jQuery 1.x behavior.
Instructions for including external jQuery / overriding the embedded one are here:
