That's a progression, for each step you increase the total next number by 8+6.

So
1. 3+8=11
2. 11+8+6=25
3. 25+8+6+6=45
4. 45+8+6+6+6=71
5. 71+8+6+6+6+6=103
6.103+8+6+6+6+6+6=141
7.141+8+6+6+6+6+6+6=185
8.185+8+6+6+6+6+6+6+6=235
9.235+8+6+6+6+6+6+6+6+6=291

Parallelogram R S T U is shown. Diagonals are drawn from point R to point T and from point U to point S and intersect at point V

Answer:

Option C.

Step-by-step explanation:

Given information: RSTU is a parallelogram, Digonals RT and SU intersect each other at point V, UV=(x-3) and VS=(3x-13).

According to the properties of a parallelogram, the diagonals of a parallelogram bisect each other.

Using the properties of parallelogram we can say that point V divides the diagonal SU in two equal parts, UV and VS.

$VS=UV$
