Consider a sequence who’s first three terms are 5,15,45... write an equation for this sequence in explicit form

y=x*3

Step-by-step explanation

step one: find how many times dose 5 go into 15

15/5=3

then we can do the same thing to see how many 15's can go into 45

45/15=3

therefore, the answer is 3

only 10/60 isn't equivalent

hope this : )
