Answer:
16
Step-by-step explanation:
group the first 2 terms into (8*8) and the second two into (8*6). this gets you 8*8-8*6 which can be grouped into 8*2 which is 16
Regroup terms
2(x + 2) = 1
Divided both sides by 2
x + 2 = 1/2
Subtract 2 from both sides
x = 1/2 - 2
Simplify 1/2 - 2 to -3/2
<u>x = -3/2</u>
Answer:

Step-by-step explanation:
•Using the formula the first term is a1 = −3
•Using the formula the second term is a2 = −1
•Using the formula the third term is a1 = 6
•Common difference formula:
a2 - a1 = (-1) - (-3) = 2
