Answer:
At president bush's inauguration in 2005, the newspaper headline stated there were about 400,000 people in attendance.
Now, rounding to nearest ten thousand the greatest number will be: 404999.
And the smallest number will be : 395000
So, the largest number of people who could have been here is 404999.
And the smallest number of people who could have been here is 395000.
the answer is 18
Step-by-step explanation:
aₙ= 4n+11
the sequence 15, 19, 23, 27
is AP with the first term 15 and
the common difference 19-15=23-19=27-23= 4
aₙ= a₁+(n-1)d
aₙ= 15+(n-1)*4= 15+4n- 4= 4n+11
Answer: 1
