Answer:
-4
Step-by-step explanation:
1. Use the distributive property to get 6x + 36 = -2x + 8 + x
2. Combine like terms 6x + 36 = -x + 8
3. Subtract 36 on both sides. 7x + 36 = 8 > 7x = -28
4. Divide by 7
-28/7 = -4 x=4
A proportion<span> is a name we give to a statement that two ratios are equal. It can be written in two ways: two equal fractions, or, using a colon, a:b = c:d.</span>
Answer:
the explicit formula for the geometric sequence 2,6,18,54 is 
2,6,18,54
Step-by-step explanation:
In the sequence given: 2,6,18,54
The common ration is 3 because
a₁ = 2
a₂= 2*3 =6
a₃ = (2*3)*3 = 2*3^2 = 18
a₄= (2*3*3)*3 =2*3^3 = 54
Here we see for a₂ 3 has power 1, for a₃ 3 has power 2 and so on.
So, the formula will be

Here aₙ is the no of term.
a₁ is the first term of the sequence
and r is the common ratio among the sequence.
