The first five terns of the sequence are - 1,4,1,4,1
<h3>What is a sequence?</h3>
A sequence is an enumerated group of items in mathematics where repetitions are permitted and order is important. It has members, just like a set does. The length of the sequence is determined by the number of items.
an = 5 - a n-1
a1 = 1
a2 = 5 - (1) = 4
a3 = 5 - (4) = 1
a4 = 5 - (1) = 4
a5 = 5 - (4) = 1

hope this helps!! just use the formulas and substitute
If factors are only rounded up, then the estimate is an overestimate. If factors are only rounded down, then the estimate is an underestimate. When some factors are rounded up and some are rounded down, it is harder to tell whether the estimate is an overestimate or an underestimate.
Assuming you meant is
The answer would be :

However, your equation seems weird :o
Answer:
76
Step-by-step explanation:
4^2 x 5^2 - 18^2
PEMDAS is our acronym for order of operations: Parentheses, exponents, multiplication, division, addition, subtraction.
Since we have no parentheses, we'll calculate the numbers and exponents (PEMDAS) first. "to the power of 2" is also called "squared" and means multiplying that number by itself.
(4x4) x (5x5) - (18x 18)
=16 x 25 - 324
Now we multiply: (PEMDAS)
= 400 - 324
then subtract: (PEMDAS)
=76
