Which sequences are arithmetic?check all that apply.

4vir4ik [10]

ANSWER

Option C and E

EXPLANATION

An arithmetic sequence has a constant difference among the consecutive terms.

The sequence

$18,5.5,-7,-19.5,-32,...$

has a constant difference of -12.5

$d = 5.5 - 18 = - 7 - 5.5 = - 19.5 - - 7 = - 32 - - 19.5 = - 12.5$

The sequence

$16,32,48,64,80,...$

also has a common difference of 16

$d = 32 - 16 = 48 - 32 = 64 - 48 =80 -64 = 16$

Therefore correct answers are C and E
