A recursive rule for an arithmetic sequence is a₁=4;a_n=a_(n−1)−3 .

steposvetlana [31]

The explicit formula of the arithmetic sequence:

$a_n=a_1+(n-1)d$

d - common difference

We have the recursive formula of an arithmetic sequence:

$\left\{\begin{array}{ccc}a_1=4\\a_n=a_{n-1}-3\end{array}\right$

Therefore we have:

$a_1=4,\ d=-3$

Substitute:

$a_n=4+(n-1)(-3)=4-3n+3=7-3n$

<h3>Answer: aₙ = 7 - 3n</h3>

Which answer is closest to the true value of the expression:

d1i1m1o1n [39]

$(9.1\times10^4)(1.1\times10^{-5})(log10^{-13})(1000)\\\\=(9.1\times1.1)(10^4\times10^{-5}\times10^3)(-13log10)\\\\=10.01\times10^{4-5+3}(-13)\\\\=-130.13\times10^2\\\\=-13013\approx-13000\\\\Answer:(c).$
