The values of r and a1 are (c) r = 8; a1 = 0.45
The geometric progression is given as:
an = 0.45 * 8^(n - 1)
The nth term of a geometric progression is represented as:
an = a1 * r^(n - 1)
Where:
By comparing an = 0.45 * 8^(n - 1) and an = a1 * r^(n - 1), we have the values of r and a1 to be
r = 8; a1 = 0.45
Hence, the true option is (c)
