I don’t understand what this question says, please help :(

a(15) = 131

Step-by-step explanation:

Explicit Arithmetic Sequence Formula: an = a1 + d(n - 1)

We are given a1 and d, so plug them in:

an = 5 + 9(n - 1)

To find the 15th term, plug 15 in for n:

a(15) = 5 + 9(15 - 1)

a(15) = 5 + 9(14)

a(15) = 5 + 126

a(15) = 131

Step-by-step explanation:

d = 9 ----> d is common difference

----> first term

In arithmetic sequence, the difference between two terms is constant.

to find nth term,

0.16 or 16%

step-by-step explanation:

lets take a coin for example.

if you toss it twice, it has a 1/4 chance of landing on heads both times because 1/2 * 1/2 is 1/4.

with the cards, the chance of picking dog is 0.4. having two people pick one is like picking a card twice in a row. so 0.4 * 0.4 is 0.16, or 16%

the answer is c hope it
