Answer:
ai = 190.0
Step-by-step explanation:
I'll presume the sequence is arithmetic, simply because assuming the series is mathematical, there is more than one solution.
Assuming the series is comprised of numbers in an arithmetic progression, you will have... (see attachment for better explanation and step by step.)
The answer is 566m because 147 plus 147 and 136 plus 136 equals 566
A•b = (3×10) + (-2×-4) + (-7×-2) = 30 + 8 + 14 = 52
Answer:
x ≥ 4
Step-by-step explanation:
Start with: 5x - 9 ≥ 11
Add 9 to both sides: 5x - 9 + 9 ≥ 11 + 9
Divide both sides by 5: 
Simplify: x ≥ 4
Since you are not dividing both sides by a negative number, the greater than or equal to sign faces the same direction.
