When given the lengths of the diagonals of a kite, which statement best explains how to find the area? A. Add the links
B. Add the links then divide by 2
C. Add the links then multiply by 2
D. Multiply the links then divide by 2

D

Step-by-step explanation:

The area (A) of a kite is calculated as

A = × d₁ × d₂ ( d₁ and d₂ are the diagonals )

This can be represented as

Multiply the diagonals then divide by 2 → D

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
