Given the arithmetic sequence a1,a2,a3,a4 28, 33, 38, 43 what is the value of a11?

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

This is too long-standing now get out
