I assume you're asking to solve for the n-th term in the sequence,
.
From the given recursive rule,

and by substitution,

Similarly,


The pattern continues, so that we can write the n-th term in terms of the 1st one:

So the first few terms of the sequence are
{10, 12, 14, 16, 18, 20, …}
Answer:
x = 28.8
Step-by-step explanation:
Using the Sine rule in the triangle then
=
( cross- multiply )
x × sin87° = 43 × sin42° ( divide both sides by sin87° )
x =
= 28.8
Ratio of the sides of the triangles,
<em>2 : 3 : 4 </em>
Let's consider each side to be
2x,3x and 4x
Therefore the perimeter of the triangle is,
<em>2x + 3x + 4 x = 9x </em>
The shortest side is 15 inches.
We know that the smallest value in the above ratio is 2
Therefore,
2x = 15 inches
x = 7.5 inches
<u>☞</u><u>Perimeter of the triangle </u>
= 9x
= 9 * 7.5 inches
= <u>67.5 inches</u>
