Question

Ch 10 algebra 1,3,5,7,9​

Answer 1

Answer:

This is clearly an arithmetic sequence because the terms differ by 2 each time.

To find the nth term rule we need:

a value for the first term , a

and a value for the common difference d

Step-by-step explanation:

$Tn=a+(n−1)d$

$a=1andd=2$

$Tn=a+(n−1)d$

$Tn=1+(n−1)2$

$Tn=1+2n−2$

$Tn=2n−1$
