Checking if the sequence is an arithmetic sequence
7 - 1 = 6
13 – 7 = 6
Therefore the sequence is arithmetic, with a_0 = 1 and d = 6
a_n = a_0 + (n-1)d
a_30 = 1 + (29)(6)
= 175
Therefore the 30th term is 175.

Answer:
n=35
Step-by-step explanation:
Isolate the variable by dividing each side by factors that don't contain the variable
Answer:4\left(1-4r\right)+5\left(r-7\right)=-11r-31
Step-by-step explanation:
Area of the bases
<span>2π<span>r2</span>=2π∗784=1568π
</span>circumference of base
<span>2πr=56π
</span>extension of the height
<span>2πr∗h=56π∗48=2688π
</span>bases plus none base surface is total surface
<span><span>1568π+2688π=4256π</span></span>
