I need help with this question, thanks!

Answer:
50
Step-by-step explanation:
magic and apparently this needs to be 50 characters so yeah
This is super simple, try and follow along with me.
so he has 16 red beads
he has 2 less yellow beads then red beads, 16 - 2 = 14 yellow beads
he also has 4 more green beads then red ones, 16 + 4 = 20
16 + 14 + 20 = 50 beads
