You posted a lot of questions. I'll do the first four problems to get you started.
============================
Problem 1
This sequence is arithmetic because we add the same amount (4) each time to get the next term. The first term is -2. The first five terms are: -2, 2, 6, 10, 14
============================
Problem 2
This sequence is geometric. We multiply each term by 1/4 to get the next term. We start with 8 as the first term. The first five terms are 8, 2, 1/2, 1/8, 1/32.
============================
Problem 3
Similar to problem 1. This time we're adding -19 to each term to get the next one. The starting term is -6. This sequence is arithmetic and the first five terms are -6, -25, -44, -63, -82
============================
Problem 4
Similar to problem 2. This sequence is geometric with common ratio 2/3. First term is 6. The first five terms are 6, 4, 8/3, 16/9, 32/27
I think -3; If the final par was -8, you would subtract (-4 + 2), you would get -6. Then you just divide it in half because it said he scored the same in rounds 3 and 4, leaving you with -3.
Answer:
It is A
Step-by-step explanation:
6 x 15 = 90
9 x 15 = 135

Write down some equations that express what you know.
A = 2*30 + 3x
K = 1*30 + 5x
A+K = 210
Substitute the expression for A in the A+K=210 expression
2*30 +3x + K = 210
Now substitute the expression for for K
2*30 + 3x + 1*30 + 5x = 210
Multiply and combine terms
60 + 3x + 30 + 5x = 210
90 + 8x = 210
Subtract 90 from both sides
8x = 120
Divide both sides by 8
x = 120/8 = 15
