Find the recursive formula of the arithmetic sequence
14,30,46,62

Answers

Answer:

$a_n=a_(n-1)+16$

Step-by-step explanation:

The given arithmetic sequence is

14,30,46,62

The first term of this sequence is

$a_1=14$

The common distance is obtained by subtracting a subsequent term from a previous term;

d=30-14

The common difference is

d=16

The recursive formula is given by:

$a_n=a_(n-1)+d$

We now plug in the known value for the common difference to get;

$a_n=a_(n-1)+16$

a 290 inch pipe is cut into two pieces one piece is four times the length of the other find the links of the two pieces

Answers

290=x+4x
290=5x
x=290/5
x=58 inch (the shortest piece)

290-58=232 inch (the longest piece)

I would set an equation up like this, where two pieces, one being 4 times as long as the other, are 290 inches together.

4x + x = 290

Now, simplify and solve:

5x = 290

x = 58

Now that we have x, we know the length of the smaller piece. The other piece, however, is 4x.

4x = 4(58) = 232

The lengths of the pieces are 58 and 232.
