yes they are spots
The number of sunspots increases at times, and decreases at others. It will not continue to increase indefinitely.
Yes. This is called sunspot extrapolation. For the past 400 years, scientists have been observing the sunspot populations. They have found a variety of qualitative (non-numerical) and quantitative (numerical) data and have concluded that the number of sunspots peaks and falls at a cycle of approximately 11 years.
The ancient Chinese were among the first to observe and document sunspots as early as the 4th century BCE. They noted these dark spots on the sun's surface, which appear in cycles, indicating the dynamic nature of the sun.
Sunspots are temporary dark spots on the Sun's surface caused by magnetic activity that inhibits the flow of heat. They are cooler and appear darker than the surrounding area of the Sun, indicating intense magnetic activity. Sunspots can vary in size and shape and typically last for a few days to a few weeks.
Sunspots are temporary dark spots on the sun caused by magnetic activity. They do not directly warm the Earth. However, changes in solar activity, including sunspots, can affect Earth's climate by varying the amount of solar radiation reaching the planet.
The study of sunspots began back in 1609 by Galileo. Galileo noticed the sunspots while gazing through a telescope. The actual study did not commence until 1612.
We call them sunspots, but dark and cool are relative terms. A sunspot is dark only relative to the surrounding solar surface, but still intensely bright compared to your common household light bulb. It's cooler than the surrounding solar material, but still hot enough to vaporize a spaceship and anyone inside it in a fraction of a second.

Sunspots are dark spots visible on the sun that are caused by intense magnetic activity and causes the area where the sunspots are seen to cool the temperature at that area.
Sunspots are the temporary dark spots on the surface of the sun, specifically the photosphere. Sunspots can get as big as 50,000 km long. Sunspots can interrupt terrestrial magnetism.
Pairs? No. Sunspots can be singular, but more often develop in clusters.
