For the arithmetic sequence (2 - x),

Question

(-6 + 2x), (x + 2), solve for x and find t10.

Would I have to start off like this below:::

an = a1 + (n - 1) d

d = (-6 + 2x)-(2 - x) = (x + 2)-(-6 + 2x)

Answer 1

correct, just solve
(-6 + 2x)-(2 - x) = (x + 2)-(-6 + 2x)
....
I got
x = 4

so the sequence is
-2, 2, and 6
