Given
f(x) = x² - 8x + 3
To complete the square
add/subtract ( half the coefficient of the x- term )² to x² - 8x
f(x) = x² + 2(- 4)x + 16 - 16 + 3 = (x - 4)² - 13

Answer:
-7
Step-by-step explanation:
To find the common difference, you subtract a term from the term after it. For example, in the problem, you can subtract 13 from 6:
6 - 13 = -7
To check you can do the same thing with other consecutive numbers in the sequence like:
-1 - 6 = -7
16, think of 4 plus 4 plus 4 plus 4.
