Find the common difference of the arithmetic sequence -5, -14, -23, ...
BartSMP [9]

Answer:

-9

Step-by-step explanation:

<u>Given </u><u>:</u><u>-</u><u> </u>

  • A Arithmetic sequence -5 , -14 , -23 ...

And we need to find out the common difference of the Arithmetic sequence . The common difference of a Arithmetic sequence is the number which is added to a term to obtain the next term of the sequence . And it can be obtained by subtracting the consecutive terms.

<u>Sequence</u><u> </u><u>:</u><u>-</u><u> </u>

:\implies -5 , -14 , -23

<u>Common</u><u> difference</u><u> </u><u>:</u><u>-</u><u> </u>

:\implies CD = -14 -(-5) = -14+5=-9

:\implies CD = -23-(-14) = -23+14=-9

<u>Hence </u><u>the</u><u> </u><u>common</u><u> difference</u><u> </u><u>is </u><u>(</u><u>-</u><u>9</u><u>)</u><u> </u><u>.</u>
