Question

Calculate the next 3 terms and write the formula for the nth term for the following sequences. x, x+2, x+4,…

Answer 1

Answer:

Forth term = x + 6

Fifth term = x + 8

Sixth term = x + 10

Formular for nth term:

${ \tt{n _{th} = a + (n - 1)d}} \\ { \tt{{n _{th} = x + (n - 1) \times 2}}} \\ { \tt{{n _{th} =x + 2n - 2 }}}$

Answer 2

Answer:

Hello,

Step-by-step explanation:

First term of this aritmetical sequence is x+0*2

$U_1=x+0*2\\U_2=x+2=x+1*2\\U_3=x+4=x+2*2\\U_4=x+6=x+3*2\\\\n^{th}\ term\ is\ U_n=x+(n-1)*2$
