In a geometric sequence, if a3 = ‒5 and a6 = 40, determine a1, r, and an. Then write the first three terms of the sequence.

Tresset [83]

$a_4=ra_3$
$a_5=ra_4=r^2a_3$
$a_6=ra_5=r^3a_3$

$40=-5r^3\implies r^3=-8\implies r=-2$

$a_3=ra_2=r^2a_1$

$-5=(-2)^2a_1\implies a_1=-\dfrac54$

You know the first and third terms, $a_1$ and $a_3$ , so you just need to find the second term $a_2$ :

$a_2=ra_1\implies a_2=-2\left(-\dfrac54\right)=\dfrac52$

What do you say when you get off a boat

Vanyuwa [196]

Usually people love to travel via boat including me :). At some point you need to get off from boat.

Question is asking about what should we say when we get off from boat. There can be lots of answers for this question because there is no fixed rule to leave the boat.

You may say good bye or wish the people who are still on the boat.

In fact you are free to say anything in the world. :)
