Question

What is the pattern in the sequence graphed below?

Answer 1

Answer:

The correct option is B.

Step-by-step explanation:

From the given graph it is clear that the sequence is in the form of

8, 7, 6, 5, 4, 3, 2, 1, 0

It is an AP because any two consecutive terms have same difference.

The first term of the sequence is a=8 and the common difference is

$d=7-8=-1$

The nth term of an arithmetic sequence is

$a_n=a+(n-1)(d)$

Substitute a=8 and d=-1 in the above equation.

$a_n=8+(n-1)(-1)$

$a_n=8-n+1$

$a_n=9-n$

The explicit formula for this sequence is $a_n=9-n$. It means the pattern in the sequence is "Multiply the term number by –1, then add 9".

Therefore the correct option is B.

Answer 2

The answer is c add 8 to the term number...
