An=an−1−4 a1=15 to explicit formula

USPshnik [31]

Answer:

$a_n=3n-12$

Step-by-step explanation:

We are given the recursive formula:

$a_n=a_{n-1}-4, a_1=15$

This is the recursive formula for an arithmetic sequence.

The explicit formula for an arithmetic sequence is given by:

$a_n=a_1 + d({n-1} )$

Where d=3 is the common difference.

We plug in this values to get:

$a_n=15 + 3({n-1} )$

We now expand and simplify to get:

$a_n=15 + 3n-3$

We simplify to obtain:

$a_n= 3n-12$

Is 4-6 the same as 4+(-6)? Explain your response.

vova2212 [387]

Answer: Yes, 4-6 is the same as 4 + (-6).

Step-by-step explanation:

One reason why they are the same is because 4 - 6 equals -2 and 4 + (-6) also equals -2. You can turn 4 - 6 into 4 + (-6) by turning the subtraction sign to a plus sign and turn the positive 6 into a negative 6.
