What is the explicit formula for this sequence? -7, -4, -1, 2, a.) an = 8 + (b - 1)3 b.) an = -7 + (n - 1)3 c.) an = 3 + (n -1) (-7) d.) an = -7 + (n - )

If t17 = 3 (t5) in an arithmetic progression, find t1 in terms of d.

The points (1, 7) and (0, 2) fall on a particular line. what is its equation in slope-intercept form?
