That varies, depending on the type of waves - e.g., water waves, sound waves, electromagnetic waves, etc.
External force or you can say deformation force causes spring to stretch and restoring force is developed due to introduction of restoring strain in spring to restore in its original shape.
Compression, which is the "squeezing" together of molecules, and rarefaction, which is the expansion of the "squeezed" molecules back toward their original position, is the oscillatory behavior that causes sound waves. Individually, they are not types of sound waves, because for any wave you need both a disrupting force and a restoring force oscillating between each other.
The force you are exerting to stretch it, and the restoring force of the spring.
the vibration of the particles of medium of the sound waves causes the sound waves to travel

motion & waves
Let's define restoring force first: A force that tends to restore a disturbed ocean surface to a flat configuration (Intro. to Ocean Science, Douglas Segar). So a restoring force works against a wave. Those forces are gravity, surface tension, and the Coriolis effect. Gravity is the primary restoring force for most waves. Surface tension tends to acts more prevalently on capillary waves (tiny wave heights). The Coriolis effect, which is not actually a "force," is the main restoring force for waves with long periods such as tides.

The force you are exerting to stretch it, and the restoring force of the spring.
Gravity, At any instant time the restoring force is the component of gravity acting parallel to the direction of the motion.
