Пошаговое объяснение:

If we add up all the numbers in the given sequence, we get:

2+2+22+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+22+2+2+2+2+2+2+2+2+2+2+2+22+2+2+2+222+22+22+2+2+2+2+2+2+2+2+22+2+2+2+2+2+22+22+22+222+2+22+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+2+22+2+2+2+2+2+2+2+2

Simplifying this expression, we get:

= 666

Therefore, the sum of the given sequence is 666.
