we ve asked to determine first. If this isn't arithmetic sequence, remember is an arithmetic sequence. If to get from one term to the next, we're going to add a constant well, to get from negative six to negative 10 we're gonna add to get the four to get from negative 10 to negative 14 Again, we had to get it for and to get from they get a 14 to negative 18. Again, we have negative four. So this is an arithmetic sequence. Now that we know it's in our genetic sequence, they want us to find the common difference. Remember, the common difference is the constant that's getting added, which in this case is negative for, so our common difference will be negative for.
