Sum means add
sum of the 3 is
n+n+1+n+2
it add to 57
n+n+1+n+2=57
3n+3=57
minus 3 both sides
3n=54
divide both sides by 3
n=15
n+1=16
n+2=17
the integers are 15,16, and 17
1)
Let the number of fish sandwiches sold br represented by x
Then the number of grilled cheese sold is 2X
and the number of cheeseburgers 3(2x)
x + 2x + 3(2x) = 225
and solve
2)
Let x represent the no. of pounds of peanuts
Then x + 14 represents the no of pounds of the mixture
And
(2.25)x + (3.25)(14) = (2.65)(x + 14
and solve
3) Try on your own

Let

In order to prove this by induction, we first need to prove the base case, i.e. prove that P(1) is true:

So, the base case is ok. Now, we need to assume
and prove
.
states that

Since we're assuming
, we can substitute the sum of the first n terms with their expression:

Which terminates the proof, since we showed that
