Find the common ratio in the geometric sequence 4, 10, 25, 62.5, …
a. 0.4
b. 2.5
c. 15
d. 25

The common ratio in the geometric sequence 4, 10, 25, 62.5, … is B. 2.5

This is because you would multiply each numberby 2.5 to get the next number in the sequence!

Hope this helped!

Abit confused about what you mean, but i think you might be referring to slope intercept form: y = mx + bin that case b, or the y intercept is already given.(0,-1)find the slope by using the formulay2 - y1/x2 - x1the final slope will be 4/2, equivalent to 2.now your equation should look like thisy = 4/2x -1sorry if this didn’t you out!
