Answer:
x+(x+1)+(x+2)+(x+3
Step-by-step explanation:
We know that
√1800-----> √[2³*3²*5²]----> (√2*√2*√2)*(√3*√3)*(√5*√5)
using the table
√2=1.41421
√3=1.73205
√5=2.23606
then
(√2*√2*√2)*(√3*√3)*(√5*√5)=(√2)³*(√3)²*(√5)²
=(1.41421)³*(1.73205)²*(2.23606)²
=2.83*3*5
=42.45
the answer is
42.45
I don’t understand math either

Answer:
<em>The 15th term is 10.25</em>
Step-by-step explanation:
<u>Sequences</u>
The given sequence:
-0.25, 0.5, 1.25, 2, 2.75...
can be categorized as an arithmetic sequence. To better know, we try to find a common difference between successive terms:
0.5 - (-0.25) = 0.75
1.25 - 0.5 = 0.75
2 - 1.25 = 0.75
Once we are certain it's an arithmetic sequence, we find the general term by using the formula:
Where n is the number of the term, a1 is the first term, and r is the common difference. We have already found that:
r=0.75
a1=-0.25
The 15th term (n=15) is:
The 15th term is 10.25
