The sum of the first 10 terms of the sequence 4, -12, 36, -144 is -59058
The given geometric sequence is:
4, -12, 36, -144
The first term, a = 4
The common ratio,
Since we are looking for the sum of the first 10 terms
The number of terms, n = 10
The sum of the first n terms of a geometric sequence is given as:
The sum of the first 10 terms of the sequence 4, -12, 36, -144 is -59058

Answer:
take lowest common factor
Step-by-step explanation:
The point slope formula is y - y1 = m(x - x1)
the value x1 is the x coordinate of a point
the value y1 is the y coordinate of a point
the value m is the slope, which is 3
therefore, x1 = -2 & y1 = 1
Then, all you do is plug in the points:
y - 1 = 3(x + 2)
NOTE: It is 3(x + 2) instead of 3(x - 2) because the formula is (x - x1). If you plug x1 in, it is (x - (-2)). 2 negatives cancel out to be a positive, so it is (x + 2)
