Question

Determine o 33º termo da Pa 2, 7, 12

Answer 1

$\Large\boxed{\begin{array}{l}\sf (2,7,12\dotsc)\\\sf r=7-2=5\\\sf a_{33}=a_3+30r\\\sf a_{33}=12+30\cdot5\\\sf a_{33}=12+150\\\sf a_{33}=162\end{array}}\checkmark$

Answer 2

$> resolucao \\ \\ \geqslant progressao \: aritmetica \\ \\ r = a2 - a1 \\ r = 7 - 2 \\ r = 5 \\ \\ \geqslant o \: 33 \: termo \: da \: pa \\ \\ an = a1 + (n - 1)r \\ an = 2 + (33 - 1)5 \\ an = 2 + 32 \times 5 \\ an = 2 + 160 \\ an = 162 \\ \\ > < > < > < > < > < > < > >$
