Alexxandr [17]

Answer: 17000000 ounces of gold were mined in that country that year.

Step-by-step explanation:

Let x represent the number of ounces of gold that were mined in that country that year.

Approximately 1,870,000 oz of gold went into the manufacturing of electronic equipment in a certain country in 1 year. This was 11% of all the gold mined in that country that year. This means that

11/100 × x = 1870000

0.11x = 1870000

x = 1870000/0.11

x = 17000000

ivolga24 [154]

Answer:

Required rule for $n^{th}$ is $a_{n}=7n-27$ .

Step-by-step explanation:

Given that,

$a_{11} = 50,\ \ d=7$

From the question: we have to write the $n^{th}$ term of Arithmetic sequence.

Arithmetic Sequence or Arithmetic progression (A.P) : It is a sequence which possess that difference between of two successive sequence is always constant.

$a_{1} ,a_{2},a_{3},a_{4}.....................a_{n-1},a_{n}$
