3,5,7,9 generalize the pattern by finding the nth term a. 3n b. n+2 c. 2n+1 d. 4n-1

C. 2n+1

Step-by-step explanation:

The sequence of numbers is

3,5,7,9

The terms are increasing at a linear rate. This means that it is an arithmetic progression. The difference between two successive terms is constant. This is the common difference. The formula for the nth term of an arithmetic sequence is expressed as

Tn = a + (n - 1)d

Where

Tn is the nth term of the arithmetic sequence.

d is the common difference of the arithmetic sequence.

n is the number of terms in the arithmetic sequence.

From the information given

a = 3

d = 5 - 3 = 7 - 5 = 9 - 7 = 2

Tn = 3 + 2(n - 1)

Tn = 3 + 2n - 2

Tn = 3 - 2 + 2n

Tn = 2n + 1

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.
