Find the fifth term in the sequence
kvv77 [185]

Method 1:

The recursive formula states that every next term is three times the previous one, plus two.

So, we have:

  • a_1 = 1
  • a_2 = 3\cdot 1 + 2 = 3+2 = 5
  • a_3 = 3\cdot 5 + 2 = 15+2 = 17
  • a_4 = 3\cdot 17 +2 = 51+2 = 53
  • a_5 = 3\cdot 53 +2 = 159+2 = 161

Method 2:

You can write the expression for a_5, and use the recursive formula until you get to the starting point:

a_5 = 3a_4+2 = 3(3a_3+2)+2 = 9a_3+8 = 9(3a_2+2)+8 = 27a_2+26 = 27(3a_1+2)+26 = 81a_1+80

Now use the fact that a_1 = 1 to get the conclusion

a_5 = 81+80 = 161

Seven hundred new chairs were delivered to a school. If each class
Natalija [7]

Answer:

24 chairs in each class needed

25 classrooms

700 chairs total

how many extra chairs

chairs will be c

t is total

t= 25×c

opposite of multiplication is division( 25 is multiplying by c) c needs to be alone

25 classrooms times chairs equal total chairs

t is 700

700=25×c

700/25=25/25c

700/25=C

c is 28

so 28 chairs for 25 classrooms

they need 24 chairs per class

so there are 4 extra chairs per class

4×25 is 100

**or just multiply 25 classes and 24 chairs

25 times 24 is 600

there are 700 chairs

100 left over

so 100 extra chairs
