Find a24 in the sequence, -8, 12, 32, 52,

452

Step-by-step explanation:

nth term formula: An=a + (n - 1)d

An=nth term

a= 1st term

n=the term# u need to find

d= common difference

common difference in our case is 32-12=20

20 is the common

substitute this value into the nth term formula:

An=-8+(24-1)*20

An=-8+(24-1)*20

An=452

Hope this helps!

question 1 is 8, question 2 is 9, question 3 is 24

step-by-step explanation:

now, the numbers they give you at the top are the key. from there, you just have to plug and chug! let's try 1, 2, and 3!

key: a=3, b=5, c=6

1. a+5

remember, a=3, so we plug that in to get 3+5=8

2. 15-c

c=6, so we plug that in to get 15-6=9

3. 4b

b=6, so we plug it in to get 4*6=24
