The third term in an arithmetic sequence is 10 and the fifth term is 26. if the first term is a(1) which is an equation for the nth term of this sequence?
1) a(n) = 8n + 10
2) a(n) = 8n - 14
3) a(n) = 16n + 10
4) a(n) = 16n - 38

where is the rest of the

step-by-step explanation:

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
