Answer:
60500
Step-by-step explanation:
The sum to n terms of an arithmetic sequence is
= [ 2a₁ + (n - 1)d ]
where a₁ is the first term and d the common difference
Here a₁ = 4 and d = 7 - 4 = 3, thus
= [ (2 × 4) + (199 × 3) ]
= 100(8 + 597)
= 100 × 605
= 60500
Step-by-step explanation:
Hi there!
According to the question;
nth term (tn) = 3n+8
a).
T1 = 3*1+8
= 11
b).
t7 = 3*7+8
= 29
c).
t14 = 3*14+8
= 50
Therefore, t1 = 11, t7 = 29, t14 = 50.

Answer:
y=(6)x+b
Step-by-step explanation:
Answer:
x = 175
Step-by-step explanation:
Add 8 on both sides to get 350 = 2x. Divide 2 on both sides to get your x value which is 175.
If it was 25%, it would be a 90 degree angle. So we can calculate this using a proportion. 25/90 = 24/x. Cross multiply to get 25x = 2160. When you divide by 25 on both sides you get 86.4. So the angle should be 86 degrees. Hope this helps.
