Answer:
A. nth term = 4 + (n - 1) -3
B. nth term = -7 + (n - 1) -5
Step-by-step explanation:
A. 4, 1, -2, -5, -8
First term, a = 4
Common difference, d = 1 - 4 = -3
nth term = a + (n-1)d
nth term = 4 + (n - 1) -3
B. -7, -12, -17, -22, - 27
First term, a = -7
Common difference, d = -12 - (-7)
= -12 + 7
= -5
nth terms = a + (n - 1)d
nth term = -7 + (n - 1) -5
