Gg easy

remember
(x^m)/(x^n)=x^(m-n)
and
(x^m)^n=x^(mn)
and
(xyz)^m=(x^m)(y^m)(z^m)
and
(m/n)^a=(m^a)/(n^a)
and
x^-n=1/(x^n)

so
$( \frac{6mn^{-2}}{3m^{-1}n^2} )^{-3}$ =
$( \frac{6}{3} )^{-3}( \frac{m}{m^{-1}} )^{-3}( \frac{n^{-2}}{n^2} )^{-3}$ =
$(2^{-3})((m^2)^{-3})((n^{-4})^{-3})$ =
$( \frac{1}{2^3})(m^{-6})(n^{12})$ =
$( \frac{1}{8} )( \frac{1}{m^6})(n^{12})$ =
$\frac{n^{12}}{8m^6}$

Hello i would like help and the answer to this please; what is the nth term rule of

Paraphin [41]

Answer:

The nth term of the given sequence

$a_{n} = a_{n-1} + (2n-1)$

Step-by-step explanation:

<u><em>Explanation:-</em></u>

Given sequence -5,-4,-1,4,11,20,31

a₀ = -5

a₁ = a₀ +1 = -5 +1 = -4

a₂ = a₁ + 3 = -4+3 = -1

a₃ = a₂ + 5 = -1 +5 = 4

a₄ = a₃ + 7 = 4 + 7 =11

a₅ = a₄ + 9 = 11+9 = 20

a₆ = a₅ + 11 = 20+11 = 31

a₇ = a₆ + 13 = 31 +13 =44

and so on

The nth term of the given sequence

$a_{n} = a_{n-1} + (2n-1)$
