What reclusive formula can be used to represent the sequence 2, 6, 10, 14, 18

a(n) = a(n-1) + 4

Step-by-step explanation:

a(1) = 2    The first term is 2

a(n) = a(n-1) + 4     We add 4 to the previous term or n-1

So, we get...

a(n) = a(n-1) + 4

a(1) = 2

a(2) = a(2-1) + 4    2(1) +4   = 6

a(3) = a(3-1) +4      3(2) + 4   = 10

and so on and so forth. I hope this helps.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

(0.2)+(-8)=0.3+-3+0.3m is the equation i guess? ?
