Step-by-step explanation:
Haven't you learned how to find it without outside help ?
x² + 6x + 5 = (x + 5) (x + 1)
Answer:
A. Note that in the x-axis, i.e. the projection to the x-axis is more or less the mid point between 1 and 2. And the projection to the y-axis is really close to 1, so, the answer that best stimate the point of intersection, is A.
Answer:

Step-by-step explanation:
We have been given a recurrence relation
and the first term of the sequence
.
We can rewrite the given recurrence relation as: 
We know that if difference between two consecutive terms is always constant, the sequence is called an arithmetic sequence. So we are dealing with an arithmetic sequence with first term as 4 and common difference as 12.
We can therefore, write an explicit formula for nth terms of the sequence as.

This is the required explicit function rule for the given sequence.
