Write a recursive formula for the sequence 1, 5, 9, 13

11Alexandr11 [23.1K]

Answer:

$\bold{a(n) \ = \ a(n \ + \ 1) \ + \ 4}$

Explanation:

Sequence: 1, 5, 9, 13

Add(ing) 4 every time

$\bold{a(1) \ = \ 1}$

$\bold{\bold{a(n) \ = \ a(n \ + \ 1) \ + \ 4}}$

The diagonals of rhombus fghj intersect at point k. if side gh is equal to 3x - 10 and side jh is equal to 6x - 19, find x

exis [7]

A rhombus is a square but turned so it looks like a diamond. This means all the sides are equal. With this information we can build an equation to solve for x.

3x - 10 = 6x - 19

1) Subtract 3x from both sides.

-10 = 3x - 19

2) Add 19 to both sides.

9 = 3x

3) Divide both sides by 3.

3 = x

x =3.
