An arithmetic sequence is defined by the general term tn = 19 - (n - 1)18, where n ∈n and n ≥ 1. what is the recursive formula of the sequence?

Step-by-step explanation:

Given : General term of  arithmetic sequence :

To Find:  the recursive formula of the sequence

Solution :

To find the recursive formula of the sequence .

So, the recursive formula is :

Hence the recursive formula of the sequence is :

the answer is d

step-by-step explanation:

y+3=-4(x-2)

y+3=-4x+8

  -3         -3  

y=-4x+5

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
