393216 times 4 because you could continue it on until u get to nine
A1 is the 1st term
r is the difference, they can say "r" or "d" for the difference
1st a1 is the first term = -3
2nd "r" is the difference between each consecutive terms (coming after each other) = 1.5
the rule to get any term of the sequence as we add 1.5 each time is --> a1+(n-1)*d
a1 --> 1st term , n --> order of the term u want whether 2nd, 3rd , 25th
d --> difference
so to get the 2nd--> -3+(2-1)*1.5= -1.5
to get the 3rd --> -3 +(3-1)*1.5 = 0

The writing is confusing, but as I understand it 21 is about 20% of 104 (21x100/104). The same prosentage of 500 equals 100,96 and I would round it to 101 (the answer of the first equasion x 500/100).
4y-1.5=2y+2.5
add 1.5 to both sides
4y=4+2y
subtract 2y from both sides
2y=4
divide by 2 on both sides
y=2
Using the concept of linear pair we get the measure of angle a that is equal to 94 degree.
Two lines are given k and m
In the below attached image we can see there are two lines k and m that are intersecting .
lines that intersect meet at a common point.
Here we will use the concept of Linear pair of angles.
When two lines intersect with each other then some angles are formed (opposite angles and adjacent angles).
If the angles are adjacent to each other then the angles are known as linear pair of angles.
Using the property that the Sum of angles of linear pair is always equal to 180 degree -------A
From the figure
86 + a = 180 (From A)
a= 180-86
a= 94
So the measure of the angle a is 94 degree.
