Factorize
Expression:
Start by expressing the expression as a sum of products.
and
So;
Notice that constant 3 is common in both terms.
This can then be factorizes as:
Hence:
Answer:
a(n) = -3 - 2(n-1)
Step-by-step explanation:
The most general formula for the nth term of an arithmetic sequence (such as this sequence is) is
a(n) = a(1) + c(n-1), where c is the common difference.
Here a(1) = -3 and c = -2.
Thus,
a(n) = -3 - 2(n-1).
