Answer:

40 terms

Step-by-step explanation:

the sum to n terms of an arithmetic sequence is

$S_{n}$ = $\frac{n}{2}$ (a₁ + $a_{n}$ )

then

$\frac{n}{2}$ (- 4 - 82) = - 1720 ( multiply both sides by 2 to clear the fraction )

- 86n = - 3440 ( divide both sides by - 86 )

n = 40

the series has 40 terms

ivanzaharov [21]

Answer:

$a_{n}=5\times \left( 7\right)^{n-1}$

Step-by-step explanation:

$a_{n}=a_{n-1}\times7$

Then the common ratio = 7

Then the explicit formula is :

$a_{n}=a_{1}\times \left( 7\right)^{n-1}$

$=5\times \left( 7\right)^{n-1}$
