Select the correct answer.
what is the value of (4 x (1/2)-1).
what is the value of t=1

For this case we must substitute the values t = 1,2,3 in the given series:

For

For :

For :

We add:

So, the value is 7.

Option C

Option C.

Step-by-step explanation:

The given expression is

We have to find the sum of 3 terms of the sequence formed.

The given sequence is a geometric sequence.

Explicit formula for this sequence is in the form of

In the given formula first term a = 4

and common ratio r =

Sum of a geometric sequence is represented by the expression,

Therefore, Option C is the answer.

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
