Answer: hshebe rjwkshzbjskxicbxuxbxjdnxkskzbu
Step-by-step explanation:
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 C. 2,11,26,47,74.

Answer:
x = 5
AB = 26
BC = 39
Step-by-step explanation:
A___B___C
AC = AB + BC
65 = (5x+1) + ( 7x+4 )
65 = 12x + 5
12x = 65-5
12x = 60
x = 60/12
x = 5
AB = 5x +1 = 5(5) +1 = 25 +1 = 26
BC = 7x+4=7(5) + 4 = 35 +4 = 39
I hope I helped you^_^
