Answer:

7th term is 46,875

Step-by-step explanation:

The given geometric sequence is 3, 15, 75.....

Here the first term a1 = 3, common ratio (r) = 15/3 = 5

The nth term an = a1.r^(n-1)

To find the 7th term, plug in n = 7.

a7 = 3. (5)^(7 -1)

a7 = 3.5^6

a7 = 3*15625

a7 = 46,875

Hope this will helpful.

Thank you.

So to figure out the next number in the sequence you multply the previous number by 5
the first 7 terms are
3, 15, 75, 375, 1875, 9375, and 46875
then ad those all up and you get 58,593

Why are angles opposite each other when two lines cross called vertical angles?
Nezavi [6.7K]
They are called vertical angles because the definition of vertical is: <span>in a direction, or having an alignment, such that the top is directly above the bottom. The "angles opposite each other when two lines cross" match the definition.</span>
