Complete thissequence.-30, -22,-14, -6,2 , [?]Enter the number that goes in the green box.

Answer 1

We want to complete the sequence below.

-30, -22, -14, -6, 2

From the sequence above, we can see that

`\begin{gathered} -30+8=-22 \\ -22+8=-14 \\ -14+8=-6 \\ -6+8=2\text{ and finally } \\ 2+8=10\text{ } \end{gathered}`

So the common difference is 8.

Hence the answer is 10
