Identify the type of sequence shown in the table below and select the appropriate response. n f(n) 1 540 2 500 3 460 4 420 5 380 arithmetic sequence; common difference is −40 arithmetic sequence; common difference is 40 geometric sequence; common ratio is −40 geometric sequence; common ratio is 40

arithmetic sequence; common difference is −40

Step-by-step explanation:

An arithmetic sequence is a sequence in which each term is found by adding a constant, called the common difference, to each previous term.

In this sequence, we go from 540 to 500 to 460, etc.  Each time we are subtracting 40.  This is the same as adding -40; this makes the sequence arithmetic.

step-by-step explanation:

it's is b

step-by-step explanation:

yes it represnts a functio, their are not 2 of the same numbers on the both sides
