Answer:
First question: A, Second question: B
Step-by-step explanation:
0.5= 1/2
0.25= 1/4
0.4= 2/5
Now, insert these numbers, as fractions, back into the equation:

Following PEMDAS you will get 1 as your answer.
Assuming n starts at 0, the fourth term would be n=3. c(3)=-7+6(2)=12-7=5
If the first term is 25 and the common difference is 4. Then the 97th term of the sequence will be 409.
<h3>What is a sequence?</h3>
A sequence is a list of elements that have been ordered in a sequential manner, such that members come either before or after.
The sequence is given below.
25, 29, 33, ...., so on
Then the first term is 25. And the common difference is 4.
Then the 97th term will be given as

where
n = 97
a = 25
d = 4
Then we have
a₉₇ = 25 + (97 - 1)4
a₉₇ = 25 + 96 x 4
a₉₇ = 25 + 384
a₉₇ = 409
Then the 97th term of the sequence will be 409.
