Question

qual eo 7° termo da pg (2,6,...)

Answer 1

(2, 6, ...)

a₁ = 2

q = 6/2 ---- q = 3


a₇ = 2 . 3 ⁷⁻ ¹ ----- a₇ = 2 . 3⁶  ---- a₇ = 2 . 729 ----- a₇ = 1458

Answer 2

$\mathtt{q = A_2 \div A_1} \\ \mathtt{q = 6\div2 } \\ \mathtt{q = 3} \\ \\ \\ \mathtt{A_n = A_1 ~.~q^{n-1}} \\ \\ \mathtt{A_7 = 2~.~3^{7-1}} \\ \\ \mathtt{A_7 = 2~.~3^{6}} \\ \\ \mathtt{A_7 = 2~.~729} \\ \\ \mathtt{A_7 =1.458 } \\ \\ \\ \boxed{\boxed{\mathtt{Respsota: 1.458}}}$
