The geometric progression is given by the formula bn = 2 * (-3) ^ (n – 1).
Let’s find the fourth term of the geometric progression, that is, b4.
Solution:
b4 = 2 * (-3) ^ (4 – 1) = 2 * (-3) ^ 3 = -2 * 3 ^ 3 = -2 * 3 * 9 = -6 * 9 = -48;
This means that the fourth term of the geometric progression is b4 = -48.
