The formula for the sum of n terms in an arithmetic progression is:
S = n/2 * (2a + (n-1)d)
Here, the common difference, d, is 8 and the first term, a, is 1. Substituting these into the formula, we get:
S = n/2 * (2*1 + 8(n - 1))
S = n + 4n² - 4n
S = 4n² - 3n
The answer is A.
<h3>
Answer: y</h3>
This is because y is a factor of 5y and it's also a factor of y^2 = y*y
It's the largest common factor between the two given expressions.

Step-by-step explanation:
Answer:
the total number of outcome in step 1 = 1+2+3= 6
the total number of outcome in step 2 = 2 +2+3 = 7
hence total number of outcome = 6 x7
= 42
