Answer:
not enough to figure out :/
90,400-7,100=83,300
83,300/12=6,941.66667
Monthly Salary Rounded: 6,941.67
First term: a(1) = 4; common ratio: r = 2
Then:
a(n) = 4(2)^(n-1)
Check: Predict the 4th term using this formula:
a(4) = 4(2)^3 = 4(8) = 32 (correct)
Domain: {-4, -2, 0, 2, 4}
range: {-2, -1, 0, 1, 2}
