The Answer is-23. if not I don't know what your teachers are on
Nearest hundredth would be 800. anything below 50 in the tens place rounds down.
Step-by-step explanation:
First term(a) = 1
Common difference(d)=2-1=1
No.of term(n)=50
Sn=n÷2(n+1)=50÷2(50+1)=1275
You need to be a bit more specific on the x2. Don’t know if you mean 2x or if you’re saying x squared but I’m assuming 2x so in that case you add the like terms. 4x+2x+2x+x=9x then add the 2
9x+2 is your answer. If you were solving for x and you had an equal sign instead of the addition then your answer would be 9/2 or you could simplify that of course.
9x+2
