Answer 3

\[a_{n}=a _{1}+(n-1)d\]

Answer 4

I know the equation but trying to solve it.

Answer 5

ok

Answer 6

d=?

Answer 7

d=3

Answer 8

good

Answer 9

\[a _{1}=?\]

Answer 10

\[a _{1}\] is the first term of an arithmetic progression

Answer 11

i solved it is a,n=3n-10

Answer 12

her is another, equation Find the 47th term of each arithmetic sequence, and then write an explicit formula
for each sequence.

2) 4, 6, 8, 10, 12…

Answer 13

good job

Answer 14

a1=? and d=?

Answer 15

a1=4 and d=2 ok?

Answer 16

\[a_{n}=a _{1}+(n-1)d\]
\[a_{47}=a _{1}+(47-1)d\]
\[a_{47}=a _{1}+46d\]

Answer 17

\[a_{47}=4+46*2\]

Answer 18

the answer is a,n=50

Answer 19

no

Answer 20

ok

Answer 21

46*2=?

Answer 22

its a,n=-44

Answer 23

no is 92

Answer 24

\[a_{47}=4+92=96\]

Answer 25

now the next one, 9, 5, 1, -3, -7… Find the 47th term of each arithmetic sequence, and then write an explicit formula
for each sequence.

Answer 26

a1=? and d=?

Answer 27

a1=9 and d=(-4)

Answer 28

nice

Answer 29

\[a_{47}=a _{1}+46d\]

Answer 30

now substitute the value of a1 and d
