So, if we look at the number pattern, we can see the numbers go up by 4.
The rule is Add 4.
So, to find the next two terms, we would add 4 to the last number shown, which is 15.
15 + 4 = 19
19 + 4 = 23
So, the next two terms are →19← and →23←.
Glad I could help, and good luck!

Answer:
- 494
Step-by-step explanation:
Breaking down the summation into it;s component parts
= 4k - 
k(k + 1) ← substitute k = 19
= (4 × 19 ) - 1.5 × (19 × 20)
= 76 - (1.5 × 380)
= 76 - 570
= 494
A maxm speed of 55 mph means that the speed has to be lexx than or equal to 55
x <= 55
Click off the first one because 180 (Thea) < 225 (Eleanor). Then keep the second one and click the third and fourth one.
Try this solution:
1. m∠A=m∠L; m∠B=m∠M and m∠C=m∠N;
2. m∠B=m∠M=35° and m∠C=m∠N=95°;
3. m∠A=m∠L=180°-(m∠B+m∠C)=180-35-95=50°
answer: 50°
