The measure of angle QPR is 30 degrees
Let r, g and b represent red, green and blue.
r+g+b = 74
r=g-1
b=r+g
Again, r+g+b = 74. Let's substitutte r+g for b: r+g+(r+g) = 74.
Next, let's eliminate r. Use r=g-1. Then g-1 + g + g-1 + g = 74
Combining the g terms, 4g - 2 = 74 => 4g = 76 => g = 19
Recall that r=g-1
and
b=r+g
Find r. If r=g-1, and g=19, then r = 19-1=18
Find b: b = r+g = 18+19=37
So there are 37 blue candies, 18 red candies and 19 green candies.
Check: 37+18+19=74 ??? Yes.

That is my final answer so I maybe wrong so don't take my word for it
Answer:
Step-by-step explanation:
We have that:
When we substitute n=1, we get:
When we substitute n=2 we get:
When we substitute n=3, we get:
When we substitute n=n+1, we get:
Now
We expand and simplify to obtain:
