Answer:
5x^4
Step-by-step explanation:
FIRST SOLUTION!
first number = x
second number = x+2
third number = x+4
fourth number=x+6
fifth number=x+8
sixth number=x+10
seventh number=x+12
add all of those up and combine like terms to get 7x+42=357. Now subtract 42 from both sides to get 7x=315. Next, divide both sides by 7 to get x=45. To get the numbers, plug in 45 for x.
Your numbers should be 45,47,49,51,53,55, and 57.
It should be 6100 which rounded to the nearest ten gives 61 × 10²
