Question

Calcule o 35° termo da PA (2, 5, 8, 11,...)

Answer 1

$> \: resolucao \\ \\ \geqslant \: progressao \: \: aritmetica \\ \\ r = a2 - a1 \\ r = 5 - 2 \\ r = 3 \\ \\ = = = = = = = = = = = = = =$

$> \: o \: 35 \: termo \: da \: pa \\ \\ an = a1 + (n - 1)r \\ an = 2 + (35 - 1)3 \\ an = 2 + 34 \times 3 \\ an = 2 + 102 \\ an = 104 \\ \\ \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant$
