U need to find the equation of the line....and once u do that, sub in 0 for x and solve for y
One example is when n is 11. 11^2 + 4 = 125. 11 is odd but the 11th term of the sequence, 125, is not prime because 125 is divisible by 5 and 25.
That is just absolute value, basically what it means is take off whatever sign there was attached to it (such as a negative sign)
Answer:
The product of the original numbers: xy
The product of the altered numbers (.75x)(.5y), or 0.375xy
The product has decreased by 1 - 0.375, or 0.625, or 62.5%
