Question

Найди a14, если a1 = 0,4 и d= 2,3 а14=​

Answer 1

Ответ:

а14=0.4*(13*2.3)=11.96

Объяснение:

Если это арифметическая прогрессия то верно

Answer 2

To find $a_{14}$ in an arithmetic sequence, we can use the formula:

$a_{n} = a_{1} + (n - 1) \times d$

where:

• $a_{n}$ is the $n$th term in the sequence,
• $a_{1}$ is the first term in the sequence,
• $d$ is the common difference between terms, and
• $n$ is the term number.

In this case, $a_{1} = 0.4$, $d = 2.3$, and we want to find $a_{14}$. We can plug these values into the formula:

$a_{14} = 0.4 + (14 - 1) \times 2.3$

Now, let's calculate $a_{14}$:

$a_{14} = 0.4 + (13) \times 2.3$

$a_{14} = 0.4 + 29.9$

$a_{14} \approx 30.3$
