Given the following partial series and its sum what is the value for n that would give the series that sum?
11 + 15 + 19 + 23 ... Sn = 585

1,150 give brainliest

step-by-step explanation

2r= 2300

r =1150

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
