The first five terms are: $a_1 = 1 \\a_2 = 4 \\a_3 = 27 \\a_4= 256 \\a_5=3125$ RECALL: A sequence is geometric if there is a common ratio among consecutive terms. Note that consecutive terms do not have a common ratio. Thus, the sequence is not geometric.
To find the first five terms, substitute 1, 2, 3, 4, and 5 to the given formula. $a_1 = 1^1=1 \\a_2 = 2^2=4 \\a_3 = 3^3=27 \\a_4= 4^4=256 \\a_5=5^5=3125$ RECALL: A sequence is geometric if there is a common ratio among consecutive terms. Note that consecutive terms do not have a common ratio. Thus, the sequence is not geometric.
