Answer:

x =  \frac{3}{2}

Step-by-step explanation:

first distribute

\frac{36x - 9}{2x}  = 15

next multiply both sides by 2x

36x - 9 = 15(2x) \\ 36x - 9 = 30x

simplify

- 9 =  - 6x

divide both sides by -6

\frac{ - 9}{ - 6}  = x \\   \frac{3}{2}  = x

Write the first four terms of the sequence:<br> a = 2<br> an = a(n-1) + 4
eduard

We have sequence equation a_n=a(n-1)+4.

In this case n is a natural number (1, 2, 3, ...).

So start inserting and computing value of a_n given that you know the value of n and a.

a_1=2(1-1)+4=4 (first term)

a_2=2(2-1)+4=6 \\a_3=2(3-1)+4=8 \\a_4=2(4-1)+4=10

Hope this helps.
