What represents the recursive formula for the arithmetic sequence an=7-3(n-1)

Licemer1 [7]

Answer:

$\left\lbrace\begin{aligned}& a_{1} = 7 \\ & a_{n+1} = a_{n} - 3 && \text{for $n \ge 1$}\end{aligned}\right.$ .

Step-by-step explanation:

An arithmetic sequence could be defined using only two pieces of information:

The first term of this sequence, $a_{1}$ .
The common difference between two consecutive terms of this sequence, $d$ .

The arithmetic sequence in this question is given in the explicit form, $a_{n} = 7 - 3\, (n - 1)$ , which is equivalent to $a_{n} = 7 + (-3)\, (n - 1)$ . In the explicit form, $a_{1}$ and $d$ are described in the same equation:

$\text{$a_{n} = a_{1} + d\, (n - 1)$ for $n \ge 1$}$ .

Compare $a_{n} = a_{1} + d\, (n - 1)$ with $a_{n} = 7 + (-3)\, (n - 1)$ : $a_{1} = 7$ whereas $d = -3$ .

When an arithmetic sequence is given in the recursive form, $a_{1}$ and $d$ are specified in two separate equations:

$\left\lbrace\begin{aligned}& a_{1} = a_{1} \\ & a_{n+1} = a_{n} + d && \text{for $n \ge 1$}\end{aligned}\right.$ .

In this question, it was found that $a_{1} = 7$ whereas $d = -3$ . Hence, the corresponding recursive formula for this arithmetic sequence would be:

$\left\lbrace\begin{aligned}& a_{1} = 7 \\ & a_{n+1} = a_{n} + (-3) && \text{for $n \ge 1$}\end{aligned}\right.$ .

Mrs. Tyner drove about 150 km east from Pearland, to Houston, Texas. She

frozen [14]

Answer:

d = 167.7 m

Step-by-step explanation:

We have,

Mrs. Tyner drove about 150 km east from Pearland, to Houston, Texas. She drove about another 75 km north to Dallas.

It is required to find the approximate air distance from Pearland to Dallas, Texas.

The resultant vector will give the approximate air distance. So,

$d=\sqrt{150^2+75^2} \\\\d=167.7\ m$

So, the approximate air distance from Pearland to Dallas, Texas is 167.7 m.
