An = a1 * r^(n-1)
a1 = first term = -5
r = common ratio = -4
so ur formula is : an = -5 * -4^(n-1) <==
For this, we use the equation for arithmetic sequence. It is given as:
an = a1 + (n-1)d
where an is the value at n term, a1 is the first term and d is the common difference
For 54,
54 = 12 + (3 -1)d
d = 21
an = 12 + (2-1)21
an = 33
