Question

for gp if r=-3 and t6=1701 find a​

Answer 1

Answer:

a = -7

Step-by-step explanation:

an = a × r^(n-1)

$= a \times {r}^{n - 1} \\ t6 = a \times {r}^{6 - 1} = 1701 \\ a \times {( - 3)}^{5} = 1701 \\ a \times { (- 3)}^{5} = 7 \times {3}^{5} \\ a = \frac{7 \times {(3)}^{5} }{ { (- 3)}^{5} } \\ a = - \frac{7 \times {3}^{5} }{ {3}^{5} } \\ a = - 7$

therefore a = -7
