The sum of 5 consecutive integers is 505.what is the third number in this sequence ?

101

Step-by-step explanation:

1st integer: x

2nd integer: x + 1

3rd integer: x + 2

4th integer: x + 3

5th integer: x + 4

x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 505

5x + 10 = 505

5x = 495

x = 99

3rd integer: x + 2   = (99) + 2   = 101

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
