Question

what is the 7th and 10th term in this situation
an=2+(n-1)3

Answer 1

please help

Answer 2

is this really
\[a_n=2+(n-1)^3\] or
\[a_n=2+(n-1)\times 3\]?

Answer 3

that is it

Answer 4

there are two different expressions
which one is it?

Answer 5

the 2nd one

Answer 6

Since \[
a_n = 2+(n-1)\cdot 3
\]We can say the 7th term, \(a_7\) is: \[
a_7 = 2+(7-1)\cdot 3

\]

Answer 7

where you see an \(n\) replace it by \(7\) and get what @wio wrote above

Answer 8

But they will want you to simplify.

Answer 9

wait so wio are you correct?

Answer 10

thx

Answer 11

wats the 10th

Answer 12

What I gave you is how to find the solution, you still have to do the math to simplify.

Answer 13

The 10th term can be found with the same pattern.

Answer 14

\[
a_{\#} =2+(\#-1)\cdot 3
\]

Answer 15

wat do i have to do now simplify?

Answer 16

For example: \[
2+(7-1)\cdot 3 = 2+ (6)\cdot 3
\]

Answer 17
