Answer & Step-by-step explanation:
The formula for the nth term of a geometric sequence is given by:
an = a1 * r^(n-1)
where an is the nth term, a1 is the first term, r is the common ratio, and n is the term number.
Given that the second term is 30 and the common ratio is 2, we can write:
a2 = a1 * r
30 = a1 * 2
a1 = 15
Therefore, the formula for the nth term of the sequence is:
an = 15 * 2^(n-1)
