Top row: complete, atmosphere, sphere, harm, zone
Bottom row: breathe, effects, control, protect, ful .
The provided set of words appears to follow a pattern where each word in the top row combines the last two letters of the previous word with the first two letters of the next word.
This pattern is consistent throughout the top row:
Complete: The last two letters of "complete" are "te," and the first two letters of "atmosphere" are "at." Combining them results in "plete + at," forming "complete."
Atmosphere: Similarly, the last two letters of "atmosphere" are "re," and the first two letters of "sphere" are "sp." Combining them results in "sphere."
Sphere: Following the pattern, the last two letters of "sphere" are "re," and the first two letters of "harm" are "ha." Combining them results in "sphere."
Harm: Continuing the pattern, the last two letters of "harm" are "rm," and the first two letters of "zone" are "zo." Combining them results in "harm."
Zone: Lastly, the last two letters of "zone" are "ne," and the first two letters of "breathe" are "br." Combining them results in "zone."
On the bottom row, a different pattern seems to emerge:
Breathe: The last two letters of "breathe" are "he," and the first three letters of "effects" are "ef." Combining them results in "breathe."
Effects: Following the pattern, the last three letters of "effects" are "cts," and the first three letters of "control" are "con." Combining them results in "effects."
Control: Continuing the pattern, the last three letters of "control" are "rol," and the first three letters of "protect" are "pro." Combining them results in "control."
Protect: Following the pattern, the last three letters of "protect" are "ect," and the first three letters of "ful" are "ful." Combining them results in "protect."
Ful: It appears that "ful" is added to "con" to form "control," and the pattern may not be consistent with the rest of the words.
