Question

1. work out an expression for the nth term for each sequence:


-2,-7,-12,-17


4,9,14,19


11,7,3,-1


23,35,47,59


2. Use the nth term to work out the 100th term of each sequence in question 1.


3.


4, 4 and a half, 5, 5 and a half, 6...


Tanesha; I think the expression of the sequence is 4n + a half.


Jake; i think th expression for the nth term of the sequence is; a half n + 4.


is eithe statemen correct? Explain your answer.


Please it is for tomorrow.

Answer 1

Respuesta:

Explicación paso a paso:

1.  -2,-7,-12,-17    la secuencia es -5n-2

    4,9,14,19       la secuencia es 5n+4

    11,7,3,-1         la secuencia es -4n+11

    23,35,47,59 la secuencia es 12n+23

2. -5(100)-2=502

    5(100)+4=504

   -4(100)-11=-389

    12(100)+23=1223

3. 4, 4 1/2, 5, 5 1/2, 6 6 1/2

Correcto Jake; i think th expression for the nth term of the sequence is; n/2 + 4
