Answer:
15
Step-by-step explanation:
Given that a1 = 6
an = 3 + 2(an-1),
Substitute n = 2 into the formula
a2 = 3 + 2(a1)
a2 = 3 + 2(6)
a2 = 3+12
a2 = 15
Hence the second term of the sequence is 15

D 24
Step-by-step explanation:
Answer:
B
Step-by-step explanation:
Both of the two numbers should equal the same amount when dividing.
For example, in A
25÷15=1.666...
30÷18=1.666...
Both of these answers are the same so that means that 25/30 is equivalent to 15/18
When you're dividing B though, they don't equal the same amount
90÷15=6
105÷18= 5.833...
that means that 90/105 does NOT equal 15/18
good luck

Answer:
x = 120
Step-by-step explanation:
A regular polygon means all sides and angles are equal. If a triangle has 180 degrees total, 180 / 3 = 60. That means each angle is 60 (interior angle). That is a straight line, which is 180 degrees, 180 - 60 = 120.
