To determine the percent increase in the average number of subscribers each year from 2010 to 2015, follow these steps:

1. Calculate the total percent increase in subscribers from year 0 (2010) to year 5 (2015).
- Initial number of subscribers in year 0 (2010) = 320,000
- Number of subscribers in year 5 (2015) = 769,262
- Total percent increase = [tex]\[\left(\frac{769,262 - 320,000}{320,000}\right) \times 100\][/tex]

2. Use the total percent increase to find the average annual percent increase over the 5 years.
- Total percent increase = 140.394375%
- Number of years = 5
- Annual percent increase = [tex]\[\frac{140.394375}{5}\][/tex]

The annual percent increase in the average number of subscribers each year since 2010 was 28.078875%.

So, the percent increase in the average number of subscribers each year since 2010 was [tex]\( \boxed{28.078875} \)[/tex]%.
