Arithmetic Series and Sequences Practice

Evaluate the arithmetic series described:
1 + 3 + 5 + 7..., S₈

• 116

• 58

• 64

• 128

Evaluate the arithmetic series described:
0 - 7 - 14 - 21..., S₁₇

• -959

• -1904

• -952

• -1918

-21, -16, -11, -6, ...

Is this sequence arithmetic, geometric, or neither?

• arithmetic (common difference d = 5)

• geometric (common ratio r = 5)

• neither (no common difference OR common ratio) neither (no common difference OR common ratio)
