use both girls' expressions kaya's expression is 8n kiana's expression is 2(n+1)^{2} -2(n-1)^{2}
n=4 to predict the number of dots there will be in the fourth figure, and explain how this justified your claim about their expressions. accurately using both expressions to justify the number of dots there will be in the fourth figure while showing your work. explaining how this result justified your claim about their expressions hint: plug in each figure number for n in both girl's expressions
