Answer: 4a

<u>Step-by-step explanation:</u>

12a²b⁶ 28a⁴ 42ab³

∧ ∧ ∧ ∧ ∧ ∧

2 6 a² b⁶ 7 4 aaaa 7 6 a b³

∧ ∧ ∧ ∧ ∧

2 3 aa bbbbbb 2 2 2 3 bbb

12a²b⁶: 2 * 2 * 3 * aa * bbbbbb

28a⁴: 2 * 2 * 7 * aaaa

42ab³: 2 * 2 * 3 * 7 * a * bbb

What do they have in common? two 2s and one a

GCF = 2 * 2 * a = 4a

Enter the finite geometric series from its given description, and then enter its sum.

Mama L [17]

Answer:

$a_n= 4(-5)^{(n-1)}$

-10416

Step-by-step explanation:

a = 4

r = -5

geometric series: $a_n=ar^{(n-1)} = 4(-5)^{(n-1)}$

Determine which term = -12500:

$a_n=-12500$

$4(-5)^{(n-1)}=-12500$

$(-5)^{(n-1)} = -3125$

$(5)^{(n-1)} = 3125$

$(n-1)ln(5) = ln(3125)$

$n-1 = ln(3125)/ln(5) = 5$

$n = 5 + 1 = 6$

$a_6=-12500$

Using geometric sum series formula: $S_n=\frac{a(1-r^n)}{1-r}$

Therefore, $S_6=\frac{4(1-(-5)^6)}{1-(-5)} =\frac{-62496}{6} =-10416$
