pea plant has 14 chromosomes in diploid state , what will be the ploidy state of its endosperm and synergids

The diploid number of chromosomes in an pea plant (2n) = 14.
The haploid number n will be 7.
Endosperm of an pea plant is triploid. Hence, number of chromosomes present in endosperm 3n = 7 x 3= 21.
 
Synergid cells are haploid cells. Hence, the number of chromosomes in them will be 7.
