Rewrite the expression as
Factor 2a from the first two terms and 3b from the last two:
Factor a-2b
To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x-axis or y-axis, and if there is a vertical stretch.
Parent Function:
f
(
x
)
=

Reflection about the x-axis: None
Reflection about the y-axis: None
Vertical Compression or Stretch: None
We have that
an=<span>10 * 5n---------------> an=50*n
then
for n=1
a1=50*1=50
</span>for n=2
a2=50*2=100
for n=3
a3=50*3=150
for n=4
a4=50*4=200<span>
the answer is
</span><span>the first four terms are [50,100,150,200]</span><span>
</span>
Answer:
116
Step-by-step explanation:
Total degrees in a pentagon: 540
Therefore, x + x + 100 + 101 + 107 = 540
2x + 308 = 540
2x = 232
x = 116
