Hi Hans,
By removing  \
startlinecorrection[blank] the problem persists with the following code.
Thank you.
Fabrice


\starttext

\startitemize[n][stopper={.},style=bold]

\item La suite \m{\left(U_n\right)} est géométrique de premier terme \m{U_0 = 10} et de raison \m{q = 3 }, alors :

\startitemize[a,columns,joinedup,pack,2*broad,three][stopper={.},style=bold]

\item \math{U_4 = 22}
\item \math{U_4 = 810}
\item \math{U_4 = 10 \times  3^3}
\item \math{U_4 = 10 +  3 \times 4}

\stopitemize

\stopitemize
