Hello there! Hope I can help!

$\mathrm{Multiply\:fractions}: \:a\cdot \frac{b}{c}=\frac{a\:\cdot \:b}{c} \ \textgreater \ \frac{1\cdot \left(4t-10\right)}{2}$

$\mathrm{Apply\:rule}\:1\cdot \:a=a \ \textgreater \ \frac{4t-10}{2}$

$4t-10 \ \textgreater \ Rewrite \ \textgreater \ 2\cdot \:2t-2\cdot \:5 \ \textgreater \ \mathrm{Factor\:out\:common\:term\:}2$
$2\left(2t-5\right)$

$\frac{2\left(2t-5\right)}{2} \ \textgreater \ \mathrm{Divide\:the\:numbers:}\:\frac{2}{2}=1 \ \textgreater \ 2t-5$

Hope this helps!

Given a geometric sequence with a1=5 and a4=135 find a2.

Sergeu [11.5K]

Answer:

Step-by-step explanation:

Terms in a geometric series that are n apart will have a ratio that is r^n. Here we have terms a4 and a1, which are 4-1=3 apart, so their ratio is ...

a4/a1 = 135/5 = 27 = r^3

r = ∛27 = 3

The second term is the first, multiplied by this common ratio:

a2 = a1·r = 3(5)

a2 = 15
