Answer:

Step-by-step explanation:
Given
Sequence = Consecutive Odds

Required
The sum of the terms
A sequence of odd number has a difference of 2. So, the sequence is represented as:

Add up all terms in the sequence


After nine years the salaries will be the same
28000 3600031000 3800034000 4000037000 4200040000 4400043000 4600046000 4800049000 5000052000 52000
The sequence is to take the previous number and multiply by 4, so the sequence is
3 12 48 192 768 3072 12288
add them all up and you get 16383
The answers to this questions would be:
1. A-> (1.5, 1.5) 5. A and B-> 7 units
2. B-> (-2, -1.5) 6. C and D-> 3 units
3. C-> (-3.5, 2) 7. B and D-> 1 unit
4. D-> (0.5, 0) 8. A and D-> 8 units
