Answer:
an = 8+3(n-1)
Step-by-step explanation:
We are adding 3 each time so the common difference is 3
8+3=11
11+3= 14
14+3 =17
The formula for an arithmetic sequence is
an = a1 + d(n-1) whew a1 is the first term and d is the common difference
an = 8+3(n-1)
The area of the sector in the circle can be calculated using the formula:
A = <span>π r</span>² θ / 360
where r is the radius and θ is the area subtended by sector. So,
A = π (10)² (37/360)
The answer is the first option.
For A) you have to divide by 3. So, 15, 5, 5/3, 5/9, 5/27, 5/81, 5/243, 5/729, 5/2187.
For B) you need to multiply by 3. So, 7, 4, 1, -2, -5 -8, -11, -14, -17.
