Need help with geometric sequences <br> 30 points
NeTakaya

Answer:

a_{n} = 6(5)^{n-1}

Step-by-step explanation:

The n th term of a geometric sequence is

a_{n} = a(r)^{n-1}

where a is the first term and r the common ratio

Here a = 6 and r = 30 ÷ 6 = 5, thus

a_{n} = 6(5)^{n-1}

Please show work 3d – 4 + d = 8d – (-12)
balandron [24]

Answer:

d = -4

Step-by-step explanation:

3d – 4 + d = 8d – (-12)

3d - 4 + d = 8d + 12

4d - 4 = 8d + 12

(4d - 4d) - 4 = (8d - 4d) + 12

-4 = 4d + 12

-4 - 12 = 4d (+ 12 - 12)

-16 = 4d

-16/4 = 4d/4

d = -4
