Question

Which of the following sequences is not arithmetic?

A 1,2, 3, 4, ...
B 14,9, 16, ...
C 2,4, 6, 8, ..
D 0.-2, -4, -6,

Answer 1

B.

Explanation:

Arithmetic sequences have a definite pattern.

A is counting up by 1, C is counting up by 2, and D is subtracting by 2 to get the next number in their sequences.

B's pattern is not so definite as it jumps from 14 to 9 and then to 16.
