32,48,72,108...Arithmetic or geometric I think it is arithmetic
Then Find common difference or ratio
multiple of 12?
What are the next 3 terms
120,132,144
What is the "zero" term
12 not sure what this means though
What is the equation?
12n * n

48 - 32 = 16 = d
108 - 72 = 36 = d
d is NOT CONSTANT SO NOT arithmetic !!!!!!!
but
48/32 = 1.5 = r
108/72 = 1.5 = r
SUCCESS ! r, the ratio, is 1.5, GEOMETRIC

term n = 32 (1.5)^(n-1)
when n = 1
term 1 = 32 (1.5)^(1-1) = 32(1.5)^0
but anything^0 = 1
so
first term is 32 when n-1 = 0
32 48 72 108 162 243 364.5 546.75 etc
