1 answer:

3 0

Step-by-step explanation:

$3(2.4x+4)=4.1x+7+3.1x\qquad\text{use the distributive property}\\\\(3)(2.4x)+(3)(4)=(4.1x+3.1x)+7\\\\7.2x+12=7.2x+7\qquad\text{subtract}\ 7.2x\ \text{from both sides}\\\\12=7\qquad\text{FALSE}\\\\Answer:\ \text{Zero (no solutions)}.$

Position to term rule of 2, 6, 10, 14, 18 multiply by _____ and subtract by _____

andreyandreev [35.5K]

Answer:

Please check the explanation.

Step-by-step explanation:

Given the sequence

2, 6, 10, 14, 18

An arithmetic sequence has a constant difference and is defined as

$\:a_n=a_1+\left(n-1\right)d$

compute the differences of all the adjacent terms

$6-2=4,\:\quad \:10-6=4,\:\quad \:14-10=4,\:\quad \:18-14=4$

The difference between all the adjacent terms is the same.

Thus,

$d=4$

and

$a_1=2$

Therefore, the nth term is computed by:

$a_n=4\left(n-1\right)+2$

$a_n=4n-2$

Thus, position to term rule of 2, 6, 10, 14, 18 multiply by __4___ and subtract by __2__.
