It's significant that those are all cubed numbers, of 2, 3, 4, 5 and 7 respectively. Either someone forgot to list 216 (cube of 6) or there's some other pattern going on, like 2^3, 3^3, 4^3, 5^3/ 7^3, 8^3, (9^3, 10^3 etc.)
They are all perfect cubes. 8 = 23, 27 = 33, 343 = 73, 64 = 43 and 125 = 53.

Your sequence seems to be a cubed sequence, but you are missing 64 between 27 and 125.13 = 123 = 833 = 2743 = 6453 = 12563 = 216So, next would be 73, which equals 343.

64 should be in between 27 and 125.
