Double facts the even and odd numbers for example 2×2=4
8+ the product of 2 and a number to the third power, what it means 2×m cubed. So it is 8+2m (cubed)
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.
