Question

determine o 10° termo da pa que tem,a1 = 19, r= 3​

Answer 1

$> resolucao \\ \\ \geqslant progressao \: \: aritmetica \\ \\ an = a1 + (n - 1)r \\ an = 19 + (10 - 1)3 \\ an = 19 + 9 \times 3 \\ an = 19 + 27 \\ an = 46 \\ \\ \\ \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \leqslant \geqslant \geqslant$

Answer 2

Resposta:

a₁₀ = 46

Explicação passo a passo:

P.A.(19,

a₁ = 19

r = 3

a₁₀ = ?

fórmula:

aₙ = a₁ + (n - 1).r

a₁₀ = 19 + (10 - 1) . 3

a₁₀ = 19 +(9).3

a₁₀ = 19 + 27

a₁₀ = 46
