Write a recursive formula for an, the nth term of the sequence 1, -2, -5,…

We need two things to write the recursive formula

is the first value of this sequence. For this set of values, , since appears first.

, the common difference, is . Basically it's just the the higher term minus the previous terms. To solve for ,

So regardless of what terms you choose, the common difference will be the same. Now the general formula for a recursive function is

where is the term. Let's substitute for and in this formula.

So the recursive formula is

well my understanding of this question is they want you to use the y=14.1x -2.3 and put the coordinates they gave you onto the line segment of   y=14.1x -2.3

step-by-step explanation:

hello :

by applying the distributive property :

6 × 4.3 = 6 × ( 4 + 0.3 )

            =   (6 ×   4) + (6 ×   0.3)

            = 24 + 1.8

6 × 4.3 = 25.8
