An object that weighs 50 newtons on Earth weighs approximately 20 newtons on the planet Mercury. A rock weighs 100 newtons on Earth. What is the approximate weight of the rock, in newtons, on Mercury? 40

70

170

250

It would weight 40 newtons

Step-by-step explanation:

because something that ways 50 newtons here weighs 20 newtons on Mecury so all you do to find out how many newtons a 100 newton object weighs on Mercury multiply it by 2

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
