Solution

The oldest volcano in a chain of hotspot volcanoes would be the one farthest from the volcano that erupted last.

Here's why:

Hotspot volcanoes form over "hotspots" in the Earth's mantle where plumes of hot magma rise towards the surface. As tectonic plates move over these hotspots, new volcanoes can form. However, the older volcanoes are moved away from the hotspot and stop erupting. Over time, erosion and other geological processes can wear these old volcanoes down.

So, in a chain of hotspot volcanoes, the youngest volcano is usually the one currently erupting or the one that erupted last, which is directly above the hotspot. The older volcanoes are those that have been moved away from the hotspot by tectonic plate movement. Therefore, the oldest volcano would be the one farthest from the volcano that erupted last.
