What does consequent mean?
Consequent names whatever follows from something else. In its most common modern uses it appears in two technical settings: in logic, where a conditional statement splits into an antecedent (the 'if' part) and a consequent (the 'then' part); and in mathematics, where the consequent of a ratio such as 3:5 is the second number, five. More broadly, the word functions as an adjective meaning 'following as a natural result', so that one might say rising costs were consequent upon the shortage of raw materials. The word derives from Latin consequi, 'to follow closely', and entered English via Latin and French scholarship in the medieval period. Its register is distinctly formal, and it is rarely heard in casual conversation, though phrases like 'consequent upon' remain current in British official writing. Understanding consequent also illuminates consequence, subsequent, and sequence, all built on the same Latin root of following.
The second term of a conditional statement in logic (what follows from the antecedent), or the second term of a ratio in mathematics.
"In 'if x = 2, then x² = 4', the statement 'x² = 4' is the consequent."
Chiefly used in logic and mathematics; in general prose 'consequence' is preferred for 'a thing that follows'.
Following as a logical or natural effect or result.
"The delays were consequent upon the industrial action."
Formal; commonest in British English, often in the phrase 'consequent upon' or 'consequent to'.
Rarely needed; plural forms appear mainly in technical discussions of multiple conditionals or ratios.
"The argument rests on two distinct consequents."
In logic, the whole truth of an 'if...then' statement hangs on two named parts — the antecedent and the consequent — words inherited straight from Latin verbs of following.

Etymology of consequent
Consequent descends from the Latin verb consequi, meaning 'to follow closely or accompany', formed from com- ('together') plus sequi ('to follow'). The related noun consequentia gave rise to the scholastic term for inference, and the adjective and noun consequent passed into English through Latin learning, with established philosophical and mathematical use by the early modern period. It shares this root with consequence, subsequent, sequence, execute, and persecute — all ultimately traceable to the Indo-European root *sekʷ-, 'to follow'.

How consequent is actually used
Consequent is largely formal and technical today: philosophers and logicians use it for the 'then' clause of conditionals, mathematicians for the second term of a ratio, while general usage survives mostly in the adjective form, especially in British English in phrases like 'consequent upon'. It carries no emotional connotation, but its formal register makes it rare in everyday speech.
Easily confused with consequent
An antecedent is what comes before and gives rise to something, whereas a consequent is the result or term that follows it.
A consequence is the result or effect itself, while consequent is more often used technically (as in logic or mathematics) or adjectivally to mean 'following from'.
