Answer:
The answer is 8
Step-by-step explanation: Use the KCF method.
Keep the first number, change the second sign into multiplication, and flip the numbers on the third part, so 4/1. Now multiply 2 and 4.
-7,14,-28,<u>5</u><u>6</u><u>,</u><u>-</u><u>1</u><u>1</u><u>2</u>
an = a1(r)^n-1
a4 = -7(-2)^4-1
a4 = -7(-2)³
a4 = -7(-8)
a4 = 56
an = a1(r)^n-1
a5 = -7(-2)^5-1
a5 = -7(-2)⁴
a5 = -7(16)
a5 = -112
