The explicit formula for any term is;

Tn = 15n - 60

where n represents the term number i.e for example whether is is 10th, 11th , 14th etc

Step-by-step explanation:

Here in this question, we are told to find an explicit formula for the arithmetic sequence.

From the question, the first term a is -45, the common difference d is -30-(-45) = -15-(-30) = 15

Now to find any term at any point in time, we will be needing the explicit formula;

Mathematically; Tn = a + (n-1)d

Substituting for a and d;

Tn = -45 + (n-1)15

Tn =-45 + 15n -15

Tn = 15n -45-15

Tn = 15n -60

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.
