What is 2/3 x 2/3 x 2/3 x 2/3 in fraction form?

Determine whether the sequence is arithmetic, geometric, or neither. If the sequence is arithme \( \frac{4}{9}, \frac{8}{9}, \frac{12}{9}, \frac{16}{9}, \ldots \) Aelect the correct choice below and, if necessary, fill in the answer box to complete your choic A. The sequence is geometric with a common ratio of (Type an integer or a fraction.) B. The sequence is arithmetic with a common difference of (Type an integer or a fraction.) C. The sequence is neither geometric nor arithmetic.

\( 1 \leftarrow \quad \begin{array}{l}\text { Simplify. } \\ 3! \\ 31=\square \\ \text { (Simplify your answer. Type an integer or a fraction.) }\end{array} \)

Simplify the expression. \[ -10-(-40)+20-40=1 \]

Simplify the expression \( 22-50+2=\square \)
