Definition of Arithmetic Sequence
Arithmetic sequence is a sequence of numbers that has a constant difference between every two consecutive terms.
In other words, arithmetic sequence is a sequence of numbers in which each+term except the first term is the result of adding the same number, called the common+difference, to the preceding term.

in your case, the common+difference is d=0
the rule for n-th term of a pattern is n%5E0+%2B+0

the sum of which is given by:


let's check the sum of all terms given in your sequence:
S%287%29+=+%287%2F2%29+%281+%2B+1%29+
S%287%29+=+%287%2F2%29+%282%29+
S%287%29+=+7+..which is true

so, the answer is yes, the sequence 1,1,1,1,1,1,1 is a arithmetic sequence
