20. Which expressions are equivalent to \( - 6 z + ( - 5.5 ) + 3.5 z + 5 y - 2.5 ? \)
Select all that apply.
\( \square - 8 + 5 y + 2.5 z \)
\( \square - 2.5 z + 5 y - 8 \)
\( - 8 + 5 y + ( - 2.5 z ) \)
\( 2.5 y + ( - 2.5 z ) - 5.5 \)
\( 5 y - 8 - 2.5 z\)
\(- 2.5 z + 5 y - 8\)
\(5 y - 8 - 2.5 z\)
Given the general term of the sequence, determine the first \(5\) terms:
\(a ( n ) = ( n - 1 ) / ( n + 1 )\) *
