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.
1 + 7 âź¶ 8 + 19 âź¶ 27 + 37 âź¶ 64 âź¶ ...
As we can see, the difference between consecutive terms is not constant. Therefore, the sequence is not arithmetic.
