Okay, so I'm kinda stuck right now. "Last week Amy ran 18 miles more than Anjali. Amy ran 45 miles. Write and solve an equation to find out how many miles Anjali ran."

This is a two-step equation so you know the drill. What I got is x+8=45
Is this right? Or wrong?

= 27

Step-by-step explanation:

x + 18 = 45

   -18      -18

x = 27

Anjali ran 27 miles.

Step-by-step explanation:

So if you make that 8 an 18 it would be right. Hope this helps!

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
