In the first series, the summation applies to the whole (2n+3) inside
the parentheses, so the 3 gets summed up 5 times.
But in the second one, the summation only applies to the 2n , so
the 3 is only added after the summation is finished.
The difference between five 3s the first time and one 3 the second time
is your 12 .
Answer:
C. 2, -2, -6
Step-by-step explanation:
18, 14, 10, 6, ?
18 - 4 = 14
14 - 4 = 10
10 - 4 = 6
6 - 4 = 2
2 - 4 = -2
-2 - 4 = -6
They are subtracting each number by 4 to get the next one that continues.
Hope this helped!

A. X> lobsters
7 + x <= 18
X <= 11 lovsters.
B. (7+3+10)
x= additional lobsters
10 + x <= 24
x<= 14 lobsters
C. 24/4 = 6 lobsters
Hope this helps.
Let garret’s age be x
x + 2 + (x + 3) + 2 = 39
2x + 7 = 39
2x = 32
x = 32/2
x = 16
Garrett’s age after two years = 16 + 2 = 18
Answer: 69
Step-by-step explanation:
The two angles are a linear pair, which means that they lie on the same line. Therefore, you just have to substract angle 1 with 180.
180-111=69
