List the first five terms of the sequence an = 1n + 16n

To find the first five terms of the sequence given by a_n = 1n + 16n, we need to substitute the values of n starting from 1 to 5 into the expression.

1. For n = 1:
   a₁ = 1¹ + 16¹ = 1 + 16 = 17
2. For n = 2:
   a₂ = 1² + 16² = 1 + 256 = 257
3. For n = 3:
   a₃ = 1³ + 16³ = 1 + 4096 = 4097
4. For n = 4:
   a₄ = 1⁴ + 16⁴ = 1 + 65536 = 65537
5. For n = 5:
   a₅ = 1⁵ + 16⁵ = 1 + 1048576 = 1048577

Therefore, the first five terms of the sequence are: 17, 257, 4097, 65537, 1048577.
