The answer is 10 because it all goes up by 10
Answer:
The common ratio of a geometric series is \dfrac14
4
1
start fraction, 1, divided by, 4, end fraction and the sum of the first 4 terms is 170
The first term is 128
Step-by-step explanation:
The common ratio of the geometric series is given as:

The sum of the first 4 term is 170.
The sum of first n terms of a geometric sequence is given b;

common ratio, n=4 and equate to 170.

You'll have to adapt this problem statement to Brainly, as Brainly does not have the Segment Tool available.
"starts with 90 pencils" implies that the y-intercept is (0,90).
"gives away 15 pencils" implies a slope of -15 pencils per unit of time
Thus, the # of pencils Jabian still has is P(x) = 90 - (15 pencils / time unit)x
12X is the period of what is the period of f : R→R, f(x) = tan(x 3)?
