As we can see -15 = 5 * (-3); 45 = - 15 * (-3) and so on. This means that a_n = -3 * a_(n-1). The first term in our series is 5 so we obtain 5 - 15 + 45 - 135 + ... = summation from n equals zero to infinity of 5 * (-3)^n. (the second answer)
Numbers and figures are an essential part of our world, necessary for almost everything we do every day. As important…
