What cones nest in the sequence?

st,nd,rd,th,___, ____.

See my answer to the same question, which you posted twice.

To determine the cones that nest in the given sequence, we need to identify the numerical pattern behind the sequence first.

The given sequence starts with "st," representing 1st, followed by "nd," representing 2nd, and "rd," representing 3rd. These are the standard abbreviations used for ordinal numbers.

After 3rd, we generally use "th" to represent all other ordinal numbers. So, the missing terms in the sequence after "rd" would be "th" and "th" again:

st, nd, rd, th, th.

Therefore, the cones that nest in the sequence are "th" and "th."
