1 answer:

I'm sorry if I'm wrong, but I'm trying. I think it's -10, because if you think of it, you may think that oh, it's going to be the oppisite, so I got -10. If I'm wrong, I'm very sorry.

<h3>Answer:</h3>

761680

<h3>Explanation:</h3>

$\sf \boxed{\sum _{n=1}^{44}\:60\left(1.2\right)^{n-2}}$

Identify the following's:

First Term [a] = 60(1.2)ⁿ⁻² = 60(1.2)¹⁻² = 50

Common ratio [r] = 1.2

Total Terms [n] = 44

===========================

$\sf Geometric \ Sum \ of \ Terms = \dfrac{a(r^n - 1)}{r-1}$

===========================

Solving Steps:

$\rightarrow \sf \dfrac{a(r^n - 1)}{r-1}$

$\rightarrow \sf \dfrac{50(1.2^{44} - 1)}{1.2-1}$

$\rightarrow \sf 761679.5808$

$\rightarrow \sf 761680 \ \ \ (rounded \ to \ nearest \ integer)$
