Find the 60th term of the arithmetic sequence 4, -1, -6, ...

Step-by-step explanation:

From the three terms, we can conclude that the arithmetic sequence for this sequence is .

∴ The 60th term of the arithmetic sequence is .

Hope this helps :)

option a is correct.

step-by-step explanation:

scale factor: it is used to find proportional measurements.

proportions means having the same ratio.

scale factor is the ratio of the model measurement to the actual measurement in a simplest form.

or we can say that the ratio of any two corresponding lengths in two similar geometric figures

if the scale factor is more than 1, then it is an enlargement,

if the scale factor less than 1, then it is a reduction.

given the two geometric figure:

by definition of proportions, we have

answer:

c) the x-coordinate of the center of the circle increases by 3
