Step-by-step explanation:
for getting to next term you multiple 4, so it's an exponential sequence
a×r^n-1
1×4^n-1
sequence: 4^n-1
12th term: 4^12-1
=4^11
=4194304
hope it helps!!

Answer: y + 1 = 2 (x -1)
Step-by-step explanation:
Point slope form is:
y - y1 = m (x - x1)
Point on the line is (1, -1) and slope is 2
m = 2
y1 = -1
x1 = 1
y - (-1) = 2 (x - 1) or y + 1 = 2 (x -1)
