Final answer:
The next sunspot maximum is anticipated around 2025, based on the 11-year solar cycle, with the last peak occurring in 2014.
Step-by-step explanation:
The next sunspot maximum is expected approximately 11 years after 2014, around 2025. The 11-year solar cycle dictates that the number of sunspots on the Sun's surface waxes and wanes over an average eleven-year period. The most recent maximum was in 2014, and while the range between maxima can be 9 to 14 years, the next peak is likely by 2025, assuming the pattern holds. Note, this does not consider any significant variations that could alter typical solar behavior as seen in historic minima periods such as the Maunder Minimum.
