Question

write an equation that describes theb sequence then find the indicated term
6,10,14,18...;47th term

Answer 1

What do you notice about those numbers?

Answer 2

you add 4

Answer 3

so would it be x+4=y

Answer 4

That is one possibility, though you start at 6 so it's 6 + 4*(n-1)

There is another possibility.

Answer 5

deos that say 6 + 4 (n-1)

Answer 6

Yes, because each time you add 4 you have

\[n=1 \implies 6 + 4(1-1) = 6 + 4(0) = 6\]
\[n=2 \implies 6 + 4(2-1) = 6 + 4(1) = 10\]
\[n=3 \implies 6 + 4(3-1) = 6 + 4(2) = 14\]
\[n=4 \implies 6 + 4(4-1) = 6 + 4(3) = 18\]
