Please help:(

what exactly are you asking?

sequence of what?

I dont undersyand how to create a formula.

The worksheet is at the link above.

i see many sequences

It says you have to work out the terms asked for, create a formula.

Actually,all of them. I uave to turn this in today.

Please know I am in eight grade.

if you're old enough to learn sequences then you're old enough to learn this

Ok..'reading'

may i try o e?

sure

From my homework.

ill write in othere first amd then type it on here.

sure

a44=8+(5-1)9

number 7

is that correct?

let me check...

ok

number 7 is looking for the 50th term not the 44th

You said a1 was the last term,which in this case is 44

that means the last term is the 50th term because that's what you're looking for
make sense?

ohhhh

well, if we erased the 44, would it be correct?

nope. you used 5 as your n

im sorry.

like i said, the sequence doesn't stop at 44 so there are more than 5 terms

since you're looking for the 50th term, there would be 50 terms
make sense?

yes

good. so rewrite your solution

wait it shouldve been 50 right

a50=8+(50-1)9

right. now solve it

thatll give me the 50th term?

do you solve for a in the a50?

no... a50 means \(a _{50}\) that means 50th term

just solve the right side

-2?

no

how'd you get -2?

umm,let me tru again

web2.0calc

ooo the a50 doesnt matter when solving

yes

513?

i lost connection

back,

was i right?

you solved 8 + (50-1)9
right?

yes

did you use a calculator?

yes
i was supposed to use order of operations?

i see what you did
(8 + 50 - 1)* 9

that is wrong

*sigh* ok

you have to do (50 -1)
then multiply it to 9
then add 8

order of ops.

PEMDAS
PARENTHESIS
expoent
MULTIPLICATION
division
ADDITION
subtraction
did you forget this?

no,
thats what order of operations is

parenthesis is (50 - 1)
multiplication is (50-1)*9
addition is 8 + (50-1)*9

that means you do 50 - 1 first

o. so, i use that formula, substitute,and solve right side?

yes

THANK YOU

welcome

hi amistre

i hope im not in trouble @amistre64

finally got to the end of it :) howdy!

howdy,sir

you mean the end of my endless question?

am i in trouble

lol, not that i can see :) as long as your trying to learn that material you are fine

yes imam.

they all look to be arithmetic progressions, so you can apply the same techniques to all of them

i'd like to know though @amistre64 do you know what dn + (a-d) means?

it looks like the formula for arithmetic progression....but it looks weird

its another way to express the sequence but for n starting at 0 i believe

amistre can i fan u

dn looks really weird

dn + (a-d)
dn - d + a
d(n-1) + a

you can fan whomever you wish

...clever

have you gone over how to find the terms used: a, d, n ?

yes

good, cause one you know how to get those, the rest is just simple arithmetic

*cause once you know

d common difference

how do you find the common difference of the sequence?

subtract.

right, subtract the first term from the second term
problem 10: 7 ,13, 19, ...
d = 13-7 = 6
right?

yes sirr

and what does the "a" in the formula refer to?

a refers to a term

im going to use a different but equal notation for the formula:
\[f(n)=a+d(n-1)\]
\[f(n)=7+6(n-1)\]

you can replace \(f(n)\) with \(a_n\) if you want, its just a placeholder
