Answer:
Common difference of the sequence is -7.
Step-by-step explanation:
Given:
First term a = 5
Tenth term
= -58
we need to find the common difference d.
Now let the number of terms will be 10 since tenth term is given;
Hence n =10
Now Using Arithmetic Progression formula we get;

Now Substituting the given values in the formula we get;

Hence Common difference of the sequence will be -7.
