Question

What pattern of 7, 15,27​

Answer 1

Ok well what I did but I’m not sure if it answers your question but I did 27-15=12-7=5 and that what I got maybe it’s 5 it’s just an assumption

Answer 2

la sucesion o razon es:

x3+9/2

así:

7x3+9/2 =  21+9/2 =  30/2 = 15

15x3+9/2  = 45+9/2  = 54/2 = 27
