Spelling out the total number of strokes required to write a given
term in capital letters generates the next term.

For example, the letter "O" is constituted by one circular stroke,
while "N" and "E" respectively contain 3 strokes and 4 strokes.

Thus, the total number of strokes in "ONE" is 1+3+4 = 8, which is spelled out as "EIGHT"(in capital letters) and we observe that
this corresponds to the second term.

Now, the number of strokes required:

To write "T" = 2
To write "H" = 3
To write "I" = 3
To write "R" = 3
To write "Y" = 3

Accordingly, the total number of strokes required to write "THIRTY" = 2*2 + 3*4 = 16, which is spelled out as "SIXTEEN" in capital letters.

Consequently, the required next term is "SIXTEEN"
