Sorry if its wrong
Answer:
This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 55 gives the next term. In other words, an=a1rn−1an=a1rn-1.
Geometric Sequence: r=5r=5
This is the form of a geometric sequence.
an=a1rn−1an=a1rn-1
Substitute in the values of a1=1a1=1 and r=5r=5.
an=1⋅5n−1an=1⋅5n-1
Multiply 5n−15n-1 by 11.
an=5n−1
Answer:
yes in some cases
Step-by-step explanation:
4.a)2x+10 >27
4.b) 27-10= 17
17/2=8.5
3.a) 40-2x>7
3.b) 7-40=-33
-33/-2=16.5
So 16 students in her class
