3%5E%28n%2B1%29-3%5E%28n-2%29
recall:
3%5E%28n%2B1%29=3%2A3%5En
3%5E%28n-2%29=3%5En%2F3%5E2=3%5En%2F9
so, we have
3%5E%28n%2B1%29-3%5E%28n-2%29=3%2A3%5En-3%5En%2F9
3%5E%28n%2B1%29-3%5E%28n-2%29=%289%2A3%2A3%5En-3%5En%29%2F9
3%5E%28n%2B1%29-3%5E%28n-2%29=%2827%2A3%5En-3%5En%29%2F9
3%5E%28n%2B1%29-3%5E%28n-2%29=%2827-1%293%5En%2F9
3%5E%28n%2B1%29-3%5E%28n-2%29=26%2A3%5En%2F9
