What is the rule of add 15,subtract 10

answer:

i hope this

step-by-step explanation:

what you have is an explicit formula:

f(x) = (x + 15) - 10

f(x) = x + 5

you want the recursive.   you take the previous number and add 5 to it to get the new number.

f(x + 1) = f(x) + 5

where       f(1) = 4

              f(x) = preceding number

              f(x + 1) = new number

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
