find the sum of the geometric sequence 3, 15, 75,375, when there are 8 terms and select the correct answer below.

292,968

Step-by-step explanation:

As we know,

Sum of a geometric sequence (S) =

where,

a = first term of sequence,

r = the constant ratio,

n = number of terms in sequence.

So, according to the question,

a = 3,

r = 5,

n = 8.

by substituting the values in the above formula, we get;

⇒

⇒

a

step-by-step explanation:

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
