Here are the first five terms of a sequence.

Snezhnost [94]

Step-by-step explanation:

3 to 8= 5

8 to 17= 9

17 to 30= 13

30 to 47= 17

47 to 68= 21

68 to 93= 25

93 to 122= 29

122 to 155= 33

155 to 192= 37

difference is 4

solve by

$2 {n}^{2} - n + 2 \\ 2 {(9)}^{2} - 9 + 2 \\ 2(81) - 9 + 2 \\ 162 - 9 + 2 \\ 153 + 2 = 155$

Write three different equations that have x=5 as a solution

svlad2 [7]

Answer: The three different equations will be

$x+3=8\\\\2x-8=2\\\\4x-4=16$

Step-by-step explanation:

We have to write three equation that have x = 5 as a solution:

1) First equation will be

$x+3=8\\\\x=8-3\\\\x=5$

2) Second equation will be

$2x-8=2\\\\2x=8+2\\\\2x=10\\\\x=\frac{10}{2}\\\\x=5$

3) Third equation will be

$4x-4=16\\\\4x=16+4\\\\4x=20\\\\x=\frac{20}{4}\\\\x=5$

Hence, the three different equations will be

$x+3=8\\\\2x-8=2\\\\4x-4=16$
