The series consists of squares of natural numbers ($2^2, 3^2, 4^2$, etc.). The number 27 is a cube ($3^3$), making it the odd one out in this sequence.

In all other numbers, the sum of the first and third digits equals the middle digit (e.g., 1 + 3 = 4 for 143). For 353, 3 + 3 = 6 (not 5), making 353 the odd one out.

This is a geometric progression with a common ratio of 3. The 8th term is found using $a \times r^{n-1} = 2 \times 3^7 = 2 \times 2187 = 4374$.
