Yes. But, if the number is multiplied/divided, then it would be a geometrical.

Answer: Yes, the resulting sequence is an arithmetic sequence.

Step-by-step explanation: Given that a fixed number is added to each term of an arithmetic​ sequence.

We are to check whether the resulting sequence is an arithmetic one or not.

Let the first term of an arithmetic sequence is a and its common difference is d.

Then, the first few terms of the sequence are given by

[tex]a,~a+d,~a+2d,~a+3d,~~.~~.~~.[/tex]

Now, if we add a fixed number k to each term of the sequence, then the sequence will be pf the form :

[tex]a+k,~a+d+k,~a+2d+k,~a+3d+k,~~.~~.~~.[/tex]

Here, we notice that

first term is (a + k) and

[tex](a+d+K)-(a+k)=(a+2d+k)-(a+d+k)=(a+3d+k)-(a+2d+k)=~~.~~.~~.~~=d.[/tex]

Therefore, the difference between the consecutive terms  in the resulting sequence will also be d.

Thus, the resulting sequence is an arithmetic sequence with first term (a + k) and common difference d.

The answer is YES.
