Answer:
a=2
Step-by-step explanation:
Slope is found by (y2-y1)/(x2-x1)
Using the points, that is (5-a)/(4a-2) = 1/2
multiply both sides by the denominator 4a-2
5-a = (1/2)(4a-2)
5-a=2a-1
put like terms on opposite sides by adding a to both sides so a terms on the right, adding 1 on both sides so numbers are on the left
6=3a
divide both sides by 3

The number of plums = 4
The number of peaches = 16
The number of nectarines = 1
Let the number of peaches be = x
Let the number of nectarines be = y
Let the number of plums be = z
A box of fruit has four times more peaches than plums. This means that
The number of peaches = 4 X the number of plums.
i.e x = 4z
The box has 3 fewer nectarines than plums. This means that
Number of nectarines = number of plums - 3
i.e y = z - 3
If the box contains 21 pieces of fruit, this means that if we sum up all the peaches, nectarines, and plums in the box, we will get 21.
Peaches + Nectarines + Plums = 21
4z + z-3 + z = 21
6z =21 +3
z = 24/6
z = 4
Therefore, the number of plums = 4
The number of peaches = 4 X 4 = 16
The number of nectarines = 4 -3 = 1
The rule is +2
This is the 194th term
This is an arithmetic sequence because 2 is added every time.
2x + 1 = 389
2x = 388
x = 194
194* 2 + 1 = 389
