brainlist will be welcom :))
I know u are supposed to use formulas to do this...but it is just as easy to do it this way...that is, if u dont have many numbers...if u were looking for s20, we would have used formulas...lol
u will notice that in ur pattern, their is a difference of 5 between each number....this is an arithmetic sequence
start at 3
3 + 5 = 8
8 + 5 = 13
13 + 5 = 18
18 + 5 = 23
23 + 5 = 28
28 + 5 = 33
thats ur first 7 numbers...so just add them and u will have s7
s7 = 126
Answer:
y = (1/2)x + 2
Step-by-step explanation:
it is a straight line so it will be in the form of y = mx + c
m = gradient, c = y intercept
Reading from graph it cuts the y-axis at 2,
so c = 2
to find gradient we can pick any 2 points on the line,
e.g (0,2) and (10,7)
gradient = (y1 - y2) / (x1 - x2) = (7 - 2) / (10 - 0)
= 1/2
so the equation is y = (1/2)x + 2
