Answer:
the 30th term of the given linear sequence is -63.
Explanation:
The given sequence is in arithmetic progression whose difference is given by:
-7 - (-5) = d
d = -2
The nth term in the arithmetic progression is given by the formula:
where 'n' is the number of terms, 'a' is the first term, is the nth term, and 'd' is the difference.
Now, substitute the known terms in the above formula.
So, the 30th term of the given linear sequence is -63.
