this formula, doesn't rely on a product, relies on a "sum", or is namely an arithmetic sequence, aₙ₋₁ -3 is another way of saying, the value of the previous term minus 3, so it relies on the ordinal value of a term, so is an recursive formula, well, let's get it when n = 4.

5.6-4.9=x
.7= x is the answer not .8
Answer:
it is b
Step-by-step explanation:
took the test
Answer:
The solution is
.
Step-by-step explanation:
Given:
The inequality given is:

In order to simplify for 'x', we first isolate 'x' on one side.
Adding -4 on both sides, we get:

Now,
is an absolute value function which is defined as:

Therefore, the given inequality can be rewritten as:
and 
Therefore, the solution is
.
