Answer:
a1=1
- 4 (common difference)
Step-by-step explanation:
a1=-4*1+5=-4+5
a1=1
a2=-4*2+5=-8+5=-3
common difference=a2-a1=-3-1=-4
Answer:
1 and -4.
Step-by-step explanation:
First term is when n = 1 so it is:
-4(1) + 5 = 1.
The common difference is the coefficient of n which is -4.
For example the 2nd term = -4(2) + 5 = -3.
Common difference = 2nd term - first term
= -3 -1
= -4.
