Question

Calcule o 10º termo da PA 26 36 36

Answer 1

$\Large\boxed{\begin{array}{l}\sf(26,36,46\dotsc)\\\sf r=36-26=10\\\sf a_{10}=a_3+7r\\\sf a_{10}=46+7\cdot10\\\sf a_{10}=46+70\\\sf a_{10}=116\end{array}}\checkmark$

Answer 2

Resposta:

$\textsf{Segue a resposta abaixo}$

Explicação passo-a-passo:

$\mathsf{ PA\,(26, 36, 46\dotsc)}$

$\mathsf{a_n=a_1+(n-1)\cdot r }$

$\mathsf{ a_{10}=26+(10-1)\cdot10}$

$\mathsf{ a_{10}=26+9\cdot10}$

$\mathsf{ a_{10}=26+90}$

$\boxed{\boxed{\mathsf{ a_{10}=116}}}$
