This one is probably really easy i just don't see the sequence rule!
i dont even need the rule, just the next 3 numbers
-3,0,4,9,
you!

15,22,30 are the next 3 numbers

Step-by-step explanation:

-3,0,4,9,...

Add 3, then add 4, then add 5,

The next would be add 6

9+6 = 15

Then add 7

15+7 =22

Then add 8

22+8 = 30

The sequence is given by

an = 1/2 (n^2 + 3 n - 10)

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

step-by-step explanation:

formula

x = x1 + p/w(x2 - x1)

let the line segment ab with a(x1,y1) and b(x2,y2)

a point(x,y) divide ab in the ratio, 2: 3 the x coordinate can be written as

x = x1 + p/w(x2 - x1)

here p=2 and w = 2+3

therefore,

x coordinate can be written by using the formula, x= x1 + 2/5(x2 - x1)

similarly y coordinate y = y1 + 2/5(y2 - y1)

the answer is 3/2 and for decimal: 1.5
