Hello, I do not succeed more to have a list according to the number of columns that I chose. 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 : \startlinecorrection[blank] \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 \stoplinecorrection \stopitemize \stoptext
