Answer
$a_1 = 2$
$a_2 = 17$
$a_3 = 82$
$a_4 = 257$
Diverges. The terms are increasing without a bound as $n$ increases.
Work Step by Step
$a_n = n^4 + 1$
$a_1 = 1^4 + 1 =2$
$a_2 = 2^4 + 1 = 17$
$a_3 = 3^4 + 1 = 82$
$a_4 = 4^4 + 1 =257$
Since the values of the sequence are increasing without a bound, the sequence is diverging.
