7) $a_{n}=-11+7 n$ Find $a_{34}$

Step 1 ：The question is asking for the 34th term of the sequence defined by the formula \(a_{n}=-11+7 n\). To find this, we simply need to substitute \(n=34\) into the formula.

Step 2 ：Substitute n = 34 into the formula: \(a_{n}=-11+7 n\)

Step 3 ：Calculate the value: \(a_{n}=-11+7*34\)

Step 4 ：The 34th term of the sequence is \(\boxed{227}\)
