2,5,2,9,13,2,17 calculate the sum of the first 100 of the terms
​

2 + 5 + 2 + 9 + 13 + 2 + 17 + 2 + 5 + 2 + 9 + 13 + 2 + 17 = 100

in geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch each other at any point are said to be parallel. by extension, a line and a plane, or two planes, in three-dimensional euclidean space that do not share a point are said to be parallel.

use distributive property on all like terms and change your signs if you have a double negative or if you have positive/negative
