Complete the following series from the given options. x_zxx_yzz_xxyyy_zz
yyxz
This is a letter-series completion problem: four blanks must be filled so that the whole string settles into a regular repeating block.
The string is x _ z x x _ y z z _ x x y y y _ z z, and the aim is to expose a clean repeating grouping of x, y and z.
Reading the series in blocks, a rising pattern emerges: a group built around x, then a group around y, then a group around z, with each block growing in a controlled way.
Insert the letters of option yyxz into the blanks in order. The string becomes x y z / x x y / y z z / x x x / y y y / z z z.
This shows a tidy structure — (x y z), then (xx yy zz), then (xxx yyy zzz) — a smooth build-up of one, two and three of each letter in turn.
The other options break this symmetry: they disturb the counts within the x, y or z blocks and leave an irregular sequence.
The key idea is to test each option against the requirement of an even, growing block pattern. Hence the correct fill is yyxz.
