What is the pattern in the infinite sequence below? –3, –1, 1, 3, 5,
a. multiply the term number by 2, then subtract 5.
b. multiply the term number by 3, then subtract 6.
c. multiply the term number by 4, then subtract 7.
d. multiply the term number by 5, then subtract 8.

 The correct option is

(A) Multiply the term number by 2, then subtract 5.

Step-by-step explanation:  We are given to select the correct pattern in the following infinite sequence below :

–3,  –1,   1,   3,   5,   .    .   ..

Let a(n) represents the n-th term of the given sequence. Then, we see that

Therefore, from above, we can conclude that

Thus, the required pattern is :

Multiply the term number by 2, then subtract 5.

Option (A) is CORRECT.

plese mark mde brainliest!

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
