Question

*3n-7
*3n+7
: *3n+1
*3n?1
plz answer this question ​

Answer 1

The general term for an arithmetic sequence is

$a_n = a_1 + (n - 1)d,$

where $a_1$ is the first term , $n$ is the term number or “index”, and $d$ is the common difference.

In this case, $a_1 = 4$ and $d = 3$, so the general term would be

$a_n = 4 + 3(n - 1).$

Test: $a_4 = 4 + 3(4 - 1) = 4 + 3 \cdot 3 = 4 + 9 = 13 \checkmark.$

OPTION C IS RIGHT $\red\checkmark$
