Question

А1=2. Решение d=4. аn=А1+(n-1)×d а12-?

Answer 1

Ответ:

Пошаговое объяснение:

а₁₂ = а₁ +(n-1)d = 2 + 11*4 = 46

Answer 2

To find the 12th term $a_{12}$ in an arithmetic sequence given $a_1 = 2$ and $d = 4$ (common difference), we can use the formula for the nth term of an arithmetic sequence:

$a_n = a_1 + (n - 1) \times d$

Plug in the given values:

$a_{12} = 2 + (12 - 1) \times 4$

Now, calculate:

$a_{12} = 2 + 11 \times 4$ $a_{12} = 2 + 44$ $a_{12} = 46$

So, the 12th term in the arithmetic sequence is $a_{12} = 46$.
