Is the Sequence Arithmetic? No. Explanation: See solution.
Practice makes perfect
When a sequence is arithmetic, the difference between two consecutive terms is constant. Let's see if this is the case for the given sequence.
46 +( - 15) âź¶ 31 +( - 15) âź¶ 16 +( - 14) âź¶ 2 âź¶ ...
As we can see, the difference between consecutive terms is not constant. Therefore, the sequence is not arithmetic.
