Consider the sequence: 3, 8, 13, 18, 23, ...

suter [353]

Answer:

$a_n$ represents a particular any term and $a_{n-1}$ represents just previous term.

$a_8=38$

Step-by-step explanation:

In the given recursive formula,

$a_n= a_{n-1}+5$

$a_n$ represents $n^{th} \ term$

and $a_{n-1}$ represents just its previous term.

To find $a_8$ , first five terms are given there. We need to find its previous terms $a_6 \ and\ a_7$

$a_6 = a_{n-1}+5\\a_6= a_{6-1}+5\\a_6 = a_5 +5\\substitute \ a_5 =23\\a_6 = 23+5=28$

Similarly,

$a_7 = a_{n-1}+5\\a_7= a_{7-1}+5\\a_7 = a_6 +5\\substitute \ a_6 =28\\a_7 = 28+5=33$

Similarly,

$a_8 = a_{8-1}+5\\a_8= a_{8-1}+5\\a_8 = a_7 +5\\substitute \ a_7 =33\\a_8 = 33+5=38$

Thus $a_8 = 38$ is the answer.

Write the equation of the line with the given slope and y-intercept. slope = 1 2 y-intercept = 7 A) y = 7x + 1 2 B) y = 1 2 x +

Setler [38]

B. y=12x+7

Explanation

The slope is 12; slope=m
The yint is 7; yint=b

The equation of a line is set up as so

y=mx+b

Now we just need to replace the variables with the numbers

y=12x+7
