"This might be a treasure map!" he exclaims as he flips it over, revealing a clue: \qquadP. Point. 673673673 paces \qquadS. Cove. 861861861 paces \qquadUnder big rock "These must be the distances to the treasure!" Peter nearly wets himself. If Peter is currently facing towards Skeleton Cove, how many degrees to his left should he turn before walking 673673673 paces to the treasure? Do not round during your calculations. Round your final answer to the nearest degree.

use substitution to solve each system of equations. y = x + 5 3x + y = 25 62/87,21 y = x + 5 3x + y = 25 substitute x + 5 for y in the second equation. substitute the solution for x into either equation to find y. the solution is (5, 10)

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be
