The first four terms of the sequence are 8,12,16 and 20.
<h3><u>
What is a Sequence?</u></h3>
- A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important. Similar to a set, it has members (also called elements, or terms).
- The length of the series is the number of elements (potentially infinite). In contrast to a set, the same items might appear more than once in a sequence at various points, and unlike a set, the order is important.
- A sequence can be described formally as a function from natural numbers (the positions of the sequence's elements) to the items at each of those positions.
- An indexed family, which is a function from an index set that may not be a set of numbers to another set of elements, can be thought of as a generalization of the idea of a sequence.
Given the function is f(n) = (2n+2)2
Now, we want first four terms, therefore, putting 1, 2, 3, 4 in the sequence we get:
f(1) = (2*1+2)2 = 8
f(2) = (2*2+2)2 = 12
f(3) = (2*3+2)2 = 16
f(4) = (2*4+2)2 = 20
Hence, The first four terms of the sequence are 8,12,16 and 20.

Answer:
X = 63°
W = 60°
Y = 57°
Step-by-step explanation:
W = X - 3
Y = X - 6
X + W + Y = 180 substitute
X + (X - 3) + ( X - 6) = 3 X - 9 = 180
3X = 189
X = 63
W = 60
Y = 57
Answer: 10

Answer:
Therefore 6th year his income was $19,700.
Step-by-step explanation:
Given, Joe's annual income has been increasing in some dollar amount . The first year his income was $15,200 and 4th year his income was $17,900.
A=$17900, P= $15,200 and n = 3 year
Let 
year Joe's income was $19,700.
≈6
Therefore 6th year his income was $19,700.
