Question

Which of the following are possible explicit formulas for the nth term of the constant-velocity sequence below? 10, 16, 22, 28, ...

choices=
A. xn = 6(n - 1)
B. xn = xn-1 + 6
C. this one doesnt appear
D. xn = 4 + 6n
E. xn = 10 + 6(n - 1)

Answer 1

And xn= x1 + (n-1) v triangle +

Explanation:

Answer 2

10, 16, 22, 28, . . . is an arithmetic sequence with a common difference of 6.
xn = a + (n - 1)d
xn = 10 + 6(n - 1)
xn = 10 + 6n - 6 = 4 + 6n

options D and E are the correct answers
