Answer:
a7 = 36
Step-by-step explanation:
Here, we are to use the recursive formula to calculate the 7th term( we add the preceding term to 4 so as to get the succeeding term)
a1 = 12
using the recursive formula given in the question
a2 = 12 + 4 = 16
a3 = 16 + 4 = 20
a4 = 20 + 4 = 24
a5 = 24 + 4 = 28
a6 = 28 + 4 = 32
a7 = 32 + 4 = 36
Answer:
x=-2 y=-6
Step-by-step explanation:
x-4=4x+2
subtract x from both sides
-4=3x+2
subtract 2 from both sides
-6=3x
divide by 3 on both sides
x=-2
y=-2-4=-6
y=4(-2)+2=-8+2=-6
