Answer:
a(4) = -18
Step-by-step explanation:
The fourth term in the sequence is when n = 4. Substitute n = 4 into the rule a(n)=-6-4(n-1).
a(4) = -6 - 4(4-1)
a(4) = -6 - 4(3)
a(4) = -6 - 12
a(4) = -18
Answer:
Question 1. Multiply 4 by 2
Question 2 . 85 + 6*7 = 127
Question 3. 24 + 3*5 = 39
Question 4. 16.75 + 32.5*9 = 46
Question 5. 2*0.4^2 + 4*0.4*3 = 5.12 (Im not positive that this one is correct or not but I tried my best)
