The nth term of a sequence is 3n+5 to the 6th terms sequence
Maslowich

Answer:

Hey!

The 6th term of your sequence is 23!

Step-by-step explanation:

<u>This is how you get it...</u>

1) T6=3n+5  (the 6th term and the equation...)

2. We now do T6=3(6)+5  (3 x 6 then add 5)

3. In other words... T6=18+5

4. We work it out 18 + 5 = 23

HOPE THIS HELPS!!

Solveeee both i neeeeeedddd hellllpppp
SCORPION-xisa [38]
Short answer: C
Remark
Since b is all by itself in equation 2, Substitute it into equation 1.

2a + 3b = 5
b = a - 5                       Put this result in equation 1. Be sure and use brackets.
2a + 3(a - 5) = 5          Remove the brackets.
2a + 3a - 15 = 5           Notice the -5 inside the brackets becomes - 15
                                    Combine like terms on the left.    
5a - 15 = 5                   Add 15 to both sides
5a = 5 + 15
5a = 20                        Divide by 5
a = 20/5
a = 4

So far, c is the only possible answer.
b = a - 5
b = 4 - 5
b = - 1
