Find the tenth term in each sequence:- A. -2,-6,-18,-54 B. 7,9,12
2 answers:
Answer: A) 39,366 B) 61
<u>Step-by-step explanation:</u>
A) -2, -6, -18, -54, ....
each following term is multiplied by 3 so it is a geometric series
B) 7, 9, 12, ...
each following term is +n, so it is neither arithmetic or geometric
7 + 2 = 9
9 + 3 = 12
12 + 4 = 16
16 + 5 = 21
21 + 6 = 27
27 + 7 = 34
34 + 8 = 42
42 + 9 = 51
51 + 10 = 61 The 10th term is 61

Answer:
Step-by-step explanation:
y =4/3 x+4
slope intercept form
y = mx+b
the y intercept is 4 (0,4)
and the slope is 4/3 which is change in y over change in x
we go up 4 to the right 3
we can rewrite the slope as -4/-3
so we can go down 4 and to the left 3
this would be point (-3,0)
we have 2 points marked, now draw a line throught them
