Find the nth term of the linear sequence (A.P) (5y + 1), ( 2y + 1), (1- y),...
Answer Details
A linear sequence is a sequence in which each term differs from the previous term by a constant amount. In other words, if we subtract any term from the term that comes after it, we get the same value.
To find the nth term of the linear sequence (5y + 1), (2y + 1), (1 - y), ..., we need to first find the common difference between consecutive terms. We can do this by subtracting the second term from the first term, and then subtracting the third term from the second term:
(2y + 1) - (5y + 1) = -3y
(1 - y) - (2y + 1) = -3y - 1
Since both subtractions give us the same value of -3y, we know that the common difference between consecutive terms is -3y.
Now, we need to find the formula for the nth term of the sequence. We can use the general formula for an arithmetic progression:
nth term = a\(_1\) + (n - 1)d
where a\(_1\) is the first term, d is the common difference, and n is the term we want to find.
In our case, the first term is (5y + 1), the common difference is -3y, and we want to find the nth term. Therefore, we have:
nth term = (5y + 1) + (n - 1)(-3y)
Simplifying this expression, we get:
nth term = 5y + 1 - 3ny + 3y
nth term = (8 - 3n)y + 1
Therefore, the nth term of the linear sequence (5y + 1), (2y + 1), (1 - y), ... is (8 - 3n)y + 1.
