An arithmetic sequence has this recursive formula: {ag = 5
1er
= an-1-4
What is the explicit formula for this sequence?
O A. an = 5+(n-1)(-4)
B. a, = 5+ (n-4)(-1)
O C. an = (-1) + (n - 5)(-4)
O D. an = (-4) + (n-1)5

Step-by-step explanation:

The recursive formula given is:

Generally a recursive formula is given as:

where a = first term

d = common difference

This implies that:

a = 5

d = -4

A general formula for an arithmetic sequence is:

Therefore, the general formula for the sequence is:

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
