To classify the sequence 1, 1.7, 2.4, 3.1, we need to examine the differences between consecutive terms.
-
Difference between 1 and 1.7:
\( 1.7 - 1 = 0.7 \) -
Difference between 1.7 and 2.4:
\( 2.4 - 1.7 = 0.7 \) -
Difference between 2.4 and 3.1:
\( 3.1 - 2.4 = 0.7 \)
Since the difference between consecutive terms is constant (0.7), this sequence is classified as an Arithmetic sequence.
Thus, the correct response is:
Arithmetic
