Answer: 3</h3>
================================================
Work Shown:
15n+30 = 75
15n+30-30 = 75-30 ... subtract 30 from both sides
15n = 45
15n/15 = 45/15 .... divide both sides by 15
n = 3
Hello :
<span>f(n + 1) = f(n) + 3
f is a arithemetic </span><span>sequence of the common difference is : 3
f(1) = -4 ( the first term)
</span><span>the next term in the sequence is : f(n) = f(1) +(n-1) d .. d=3
f(n) =-4+(n-1)(3)
f(n) = 3n -7</span>
|-2| = 2<3
|-1| = 1<3
|0| = 0<3
|1| = 1<3
|2| =2<3
absolute value of positive numbers are always positive same with the negative numbers like shown in the example above.
4 hours and 15 minutes =4+15/60=4.25 hours
the average speed of the train = 250/4.25=58.82mph
