I need help b=please help me

Step-by-step explanation:

Area of a kite= (xy) / 2

A = 15.13 × 17 ÷ 2

A = 257.21 ÷ 2

A = 128.605 m2

So a quick explanation

The area of a kite is equal to xy/2 (the formula)

The find x and y you multiply the two totals of the diagoals (4.93+10.2)*(8.5×2)

The the answer you get divided by two ( 257.21÷2=128.605 )

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
