What is the recursive formula for this sequence? 10, 14, 18, 22, 26,...
O A. (
= 4
len = 2n-1 +10
=
O B.
ay = 30
an = an-1 + 4
=
C.
(ay = 10
lan= any +4
O D.
ſay = 10
Lan = an-1-4
lan

==================================================

Explanation:

The first row indicates the first term is 10. The small "1" is the index number. That means is next followed by and so on.

To generate the next term, we follow this recursive step:

It means "whatever the nth term is, we add 4 to it to get the next term "

In other words, we add 4 to each term to get the next term.

Eg: 10+4 = 14 and 14+4 = 18

The recursive step could be rewritten as based on how you frame things.

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
