ahem.........WOW
Step-by-step explanation:
Step-by-step explanation:
you cannot just put the actual numbers in and calculate ?
and you can't provide the correct problem statement, as it seems.
I assume you mean
an = 3n² - 1
a sequence starts with a1, so, n>=1
a1 = 3×1² - 1 = 3-1 = 2
a2 = 3×2² -1 = 3×4 - 1 = 12 - 1 = 11
a3 = 3×3² - 1 = 3×9 - 1 = 27 - 1 = 26
a4 = 3×4² - 1 = 3×16 - 1 = 48 - 1 = 47
a5 = 3×5² - 1 = 3×25 - 1 = 75 - 1 = 74
there, that is all there is to it. you really needed help with that ?
Answer:
it's a whole both it's fraction
Question 3) 5x-26=18x This is how the equation is written if you substitute numbers for words and x for unknown number. 18x-5x =13x divide everything by 13 to get x= -2
Question 4) 63-x=2x+3 add x to each side and subtract 3 from each side to get 60=3x divide by 3 to get x=20
Question 5) -30x= -27x-63 add -27x to each side to get -3x= -63. Divide everything by -3 to get x=21
Question 6) 12x-18= 18+13x subtract 12x from both sides to get -18=18+x subtract 18 from both sides to get x=-36
Hope this helps!
