I'm sorry i only know (A)

Step-by-step explanation:

Horizontal

28,33,38,43

the common difference can be found by subtracting the first term from the second term33 - 28 = 5so the common difference (d) = 5

an = a1 + (n - 1) * d
n = the term u want to find = 11
a1 = first term = 28
d = common difference = 5
now we sub
a11 = 28 + (11 - 1) * 5
a11 = 28 + 10 * 5
a11 = 28 + 50
a11 = 78
