We suspect you mean "geometric sequence". Multiply each term by r to get the next.

a1 = 3 . . . . . given

a2 = 3*2 = 6

a3 = 6*2 = 12

a4 = 12*2 = 24

a5 = 24*2 = 48

_____

A <em>quadratic</em> sequence is one in which second-differences are a constant. You have not provided enough information about the sequence so that more terms of a quadratic sequence could be found. While you may occasionally see problems asking you to write the formula for one of these, they are rarely studied in any detail in Algebra. At least three terms are needed before the next terms can be predicted.

Answer is 6.12

Step-by-step explanation:

pythagoras Theorem according to

$\sqrt{AB^{2}-BD^{2}} = \sqrt{AD}$

NOW WE FOUND AD,

SO, $\sqrt{AD^{2}+CD^{2} }} = \sqrt{AC^{2} } = 6.12$ YOU WILL FOUND THE SOLUTION WHEN YOU ENTER THE Value

Answer:

Step-by-step explanation:

The first triangle has the ratios 10:6:8. The next one has the ratios 5:3:x. If you have paid close attention, you can divide the first one by 2 to get the second one. 8/2 is 4 so the correct answer is 4.

Hope this helps plz mark brainliest if correct :D
