1) This is not an arithmetic sequence because it has n².
2) To find 5 first terms of this sequence, you can simply substitute n with 1,2,3,4, and 5, and calculate values of a(1),a(2), a(3), a(4) and a(5).
a(n) = 3n²- 1
n=1 a=3*1² - 1 = 3-1=2
n=2 a=3*2² - 1 = 11
n=3 a=3*3² - 1 =26
n=4 a=3*4² - 1 = 47
n=5 a=3*5² -1 = 74
2,11,26,47,74

Answer:
r=14cm
Step-by-step explanation:
Curved Surface area of a cylinder=484cm²
Height=5.5cm
r=?
Curved Surface Area=2πrh
484=2×3.142×r×5.5
484=34.56r
r=484/34.56
r=14cm
