Looking at the pattern, my opponent has chosen scissors in 3 out of 6 rounds (rounds 2, 4, and 6). They seem to favor scissors, using it half the time. They've chosen rock twice and paper only once. Since scissors appears to be their preferred choice, and they used scissors in the last round, I'll play rock which beats scissors. Additionally, if they're noticing I've played paper frequently (3 times), they might choose scissors expecting me to play paper again, making rock a strategic counter.
