Answer 6

do you knowwhatexplicit form is

Answer 7

no

Answer 8

wow somethings wrong with my space bar today 'know what explicit form is'

Answer 9

explicit form is \[a _{n}=a1+(n-1)d\]
a1= starting point
n=what you're looking for (say i need the 25th number id put 25)
d= the difference between numbers

Answer 10

k let me substitute

Answer 11

an=5+(n-1)-3

Answer 12

is that right?

Answer 13

k dont help man

Answer 14

@Preetha

Answer 15

no

Answer 16

you're expressing that you're subtracting everything in parenthesis by 3

Answer 17

no its supposed to multiply everything in parenthesis by negative 3

Answer 18

right?

Answer 19

and how do we express that?

Answer 20

parenthesis is a mathematicians best friend

Answer 21

i don't know how you'd express it man

Answer 22

can you do me a favor

Answer 23

sure

Answer 24

\[x=(a)(-b)\]
\[x=a-b\]

Answer 25

can you tell me the difference between those equations

Answer 26

What are the explicit equation and domain for an arithmetic sequence with a first term of 5 and a second term of 2? .will give medal and fan

Answer 27

sorry i coudnt see the question so i copied it down again

Answer 28

one of them is multiplication while the other is substraction

Answer 29

yes and how did we change it from subtraction to multiplication

Answer 30

parenthesis?

Answer 31

yes so \[a _{n}=5+(n-1)-3\] this is saying we are subtracting by 3 how do we fix that into multiply by -3?

Answer 32

(-3)?

Answer 33

yes

Answer 34

k so: an=5+(n-1)(-3)

Answer 35

yes

Answer 38

how do i find the domain

Answer 39

and the explicit equation?

Answer 40

we already did the explicit equation
