Question

Find the first six terms of the sequence.

a1 = 7, an = an-1 + 6

Answer 1

13, 19, 25, 31, 37, 43

0, 6, 12, 18, 24, 30

7, 6, 12, 18, 24, 30

7, 13, 19, 25, 31, 37

Answer 2

@nincompoop @Luigi0210

Answer 3

just plug-in the values 1...6 for n...

Answer 4

so its the third choice then? @Orion1213

Answer 5

is it \[a_n=a_{n-1}+6~~?\]

Answer 6

well what does a1 mean? is it the first given term or the first number i have to plug in?

Answer 7

well if \(a_1=7\) then \(a_0=7-6=1\)... moving forward...\[a_2=7+6=13\]\[a_3=13+6=19\]and so on...

Answer 8

what do you think?

Answer 9

i understand how to get the rest of the numbers i was just confused about whether or not 7 is the first term

Answer 10

but I would choose the last choice.

Answer 11

7 is really the 1st term noted as \(a_1\)

Answer 12

yes that is the correct choice... the last choice...

Answer 13

thank you! do you think you'd be able to help me with another one similar to this? @Orion1213

Answer 14

sure i still have time...

Answer 15

Find the first six terms of the sequence.

a1 = 4, an = 2 • an-1

Answer 16

so the first term would be 4? and the second one would be found how?

Answer 17

if \(a_1=4\) then \(a_2=2 \times 4=8\)... moving further...\[a_3=2 \times a_2=2\times8=16\]\[a_4=2 \times a_3=2\times16=32\]and so on...

Answer 18

got the pattern?

Answer 19

yes thank you so much!!

Answer 20

yw... :)

Answer 21

For this question did I write the equation correctly?
A certain species of tree grows an average of 0.5 cm per week. Write an equation for the sequence that represents the weekly height of this tree in centimeters if the measurements begin when the tree is 200 centimeters tall.
an= 200cm+0.5cm(n-1)

Answer 22

\(a_{n-1}\) refers to the previous term in the sequence...

Answer 23

yes you write it correct...

Answer 24

find \[a _{1+1}\] because you a1...similarly repeat \[a _{1+1+1}\] and cycle goes on...
so you will get,
\[a _{1}=a _{1}+6\] similarly do for rest of them and you will get
7, 13, 19, 25, 31, 37
Hope it's clear @faariat
