Consider the sequence: 3, 8, 13, 18, 23, ...The recursive formula for this sequence is:an = an-1 + 5In a COMPLETE sentence, expl

Akimi4 [234]

Answer:

$a_8=38$

Step-by-step explanation:

<u>Recursive sequence </u>

In a recursive sequence formula, each term $a_n$ is computed as a function of one or more previous terms. In the formula

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

n is the number of the term we want to calculate. If n=8, then the formula becomes

$a_8=a_{7}+5$

We can see $a_{n-1}$ is the previous term. It means we need $a_7$ to be able to compute $a_8$ . But we also need $a_6$ to compute $a_7$ and so on until some known data is reached. The question provides five terms, $a_5=23.$

$a_6=a_5+5=28$

$a_7=a_6+5=33$

$a_8=a_7+5=38$

$a_8=38$

2. t + 4 -5 = 0

t-1=0

t=1

4. m+3 = 12-2m

-9=-3m

3=m

5. 15+2k=45

2k=30

k=15

6. 8+5a=14-a

6a=6

a=1

7. 3x+1=2x+11

x=10

8. 40-4x=6x+10

30=10x

x=3

9. 4b+3=15-2b

6b=12

b=2

10. 16+3x =4x-12

x=28
