Answer: 
, where n = 1,2,3,4,.....
Step-by-step explanation:
The given sequence : 1, 8, 27, 64, ….
We observe that the terms are perfect cubes of consecutive integers (starting from 1) .
Terms can be written as:
First term = 
Second term=
Third term = 
Fourth term =
Thus , for any nth term ,the formula for the sequence is : , where n = 1,2,3,4,.....
Answer:
Thus, the value of x is 1.
Step-by-step explanation:
4(2x+6)=32
8x+24 =32
8x =32-24
8x =8
x =8÷8
x =1
Answer:
a(n) = a(n-1) + 4
Step-by-step explanation:
a(1) = 2 The first term is 2
a(n) = a(n-1) + 4 We add 4 to the previous term or n-1
So, we get...
a(n) = a(n-1) + 4
a(1) = 2
a(2) = a(2-1) + 4 2(1) +4 = 6
a(3) = a(3-1) +4 3(2) + 4 = 10
and so on and so forth. I hope this helps.
