vampirchik [111]

Answer:

Adam raked 340 liters of leaves.

Step-by-step explanation:

Let the leaves raked by Adam be x lt.

Given:

Leaved raked by Tapiwa = 357 lt

As per question,

Leaves raked by Tapiwa is 5% more than that of Adam.

So, x+\frac{5}{100}\times x=357\\x+0.05x=357\\1.05x=357\\x=\frac{357}{1.05}=340

Therefore, Adam raked 340 liters of leaves.

A sequence of numbers follows the rule: multiply the previous number by -2 and add 3. The fourth term in the sequence is -7. Giv
nevsk [136]

Answer:

Next 3 terms: 17, -31, 65

3 terms before -7: 2, -1, 5

Step-by-step explanation:

Fourth term in the sequence = -7

Rule for finding the next term:

a_n=-2\times a_{n-1}+3

Therefore, the fifth term:

a_5=-2\times a_4+3\\\Rightarrow a_5=-2\times -7+3\\\Rightarrow \bold{a_5=17}

Sixth term:

a_6=-2\times a_5+3\\\Rightarrow a_6=-2\times 17+3\\\Rightarrow \bold{a_6=-31}

Seventh term:

a_7=-2\times a_6+3\\\Rightarrow a_7=-2\times -31+3\\\Rightarrow \bold{a_7=65}

Let the three terms that came before -7 be: x, y, z

As per question statement:

a_n=-2\times a_{n-1}+3

-7 = -2\times z+3\\\Rightarrow -2z=-10\\\Rightarrow z=5

Again applying the given rule:

5 = -2\times y+3\\\Rightarrow y =-1

Again applying the given rule:

-1 = -2\times x+3\\\Rightarrow x =2

Therefore the 3 terms before -7 are:

2, -1, 5
