The question states that the sequence is arithmetic, which means we find the next number in the sequence by adding (or subtracting) a constant term. We know two of the values, separated by one unknown value.

We know that n is equally far from -1 and from 13; therefore n is equal to half the distance between these two values. The distance between them can be found by adding the absolute values.

(|13|+|−1|)2=arithmetic constant

142=7

The constant in the sequence is 7. From there we can go forward or backward to find out that n=6.

Answer:1120 is next term of this question

Step-by-step explanation:The question states that the sequence is arithmetic, which means we find the next number in the sequence by adding (or subtracting) a constant term. We know two of the values, separated by one unknown value.

We know that n is equally far from -1 and from 13; therefore n is equal to half the distance between these two values. The distance between them can be found by adding the absolute values.

(|13|+|−1|)2=arithmetic constant

142=7

The constant in the sequence is 7. From there we can go forward or backward to find out that n=6.

−1+7=6

13−7=6
