In mitosis, the number of chromosomes is conserved. In meiosis it is halved.

I’m still confused on the question it’s asking

Human diploid cells have 46 chromosomes (the somatic number, 2n) and human haploid gametes (egg and sperm) have 23 chromosomes (n).

So, if 2n = 78, then cells undergoing mitosis retain 78 chromosomes and cells undergoing meiosis have 39 chromosomes each.
