$- 40, - 32, - 24, - 16, .....$

Short Answer

Expert verified

The given sequence is an arithmetic sequence and the common difference is 8.

Step by step solution

Step 1. State the concept of arithmetic sequence.

In anArithmetic Sequencethe difference between one term and the next is a constant.

The nthterm of the Arithmetic sequence is given by the formula,

$a_{n} = a + (n - 1) d d = a_{2} - a_{1}$

Where, $a_{1} = a =$ first term and $d =$ common difference.

Step 2. Find the common difference of corresponding terms.

The common difference between the corresponding terms are calculated as follows.

$\begin{matrix} d = a_{2} - a_{1} = - 32 - (- 40) = - 32 + 40 = 8 \\ d = a_{3} - a_{2} = - 24 - (- 32) = - 24 + 32 = 8 \\ d = a_{4} - a_{3} = - 16 - (- 24) = - 16 + 24 = 8 \end{matrix}$

Step 3. State the Conclusion.

In the above step, the common difference is constant and its value is 8.

Hence the given sequence is an arithmetic sequence and its common difference is 8.
