False as the difference between two consecutive numbers is not a constant
Ainat [17]3 years ago
8 0

Answer:

False

Step-by-step explanation:

Given sequence,

1, 2, 3, 4, 1, 2, 3, 4, .........

Since, a sequence is called Arithmetic sequence if the difference in consecutive terms is constant,

∵ 2 - 1 = 3 - 2 = 4 - 3 = 1 - 4 ≠ 2 - 1 = 3 - 2 = 4 - 3 .......

Hence, the difference in consecutive terms is not constant,

Therefore, given sequence is not an Arithmetic sequence.
