Sequence:
1, 8, 27, 64
Pattern:
cube the nᵗʰ term number to get the current number
nᵗʰ rule formula:
aₙ = n³
let's check if our nᵗʰ rule formula is correct,
if n= 3
a₃ = (3)³
a₃ = 27 TRUE
if n= 4
a₄ = (4)³
a₄ = 64 TRUE
now it's time to solve for n, that will give us aₙ = 1000
aₙ = (n)³
1000 = n³
[tex]n \: = \sqrt[3]{1000} \\ \\ n \: = \: 10[/tex]
so the 10ᵗʰ term will give a value of 1000
