Answer:
nth term = 7n - 2
Step-by-step explanation:
a = first term = 5
d = common difference = second term - first term
= 12 - 5 =7
d = 7
a + (n-1)d
= 5 + (n -1)7
= 5 + 7n - 7 {add like terms}
= 7n - 2

Answer:
254 cm²
Step-by-step explanation:
Calculate first the total area
A = 30*20 = 600 cm²
Then calculate the area of the cercle
A= 10.5²*π = 346.36≈346 cm²
Then substract the area of the circle from the total one:
600-346= 254 cm²
