Question

the nth term of a sequence is 3n - 1

Write down the first term and the second term of the sequence

Answer 1

it all depends on what number you start your sequence with.

if you start at 0: - 0 x 3 = 0 - 1 = -1
the second term would then be 1 x 3 = 3 - 1 = 2

if you start at 1: - 1 x 3 = 3 - 1 = 2
the second term would then be 2 x 3 = 6 - 1 = 5

Answer 2

To find the first term, put n = 1 in the formula:
3*1 - 1 = 2.
To find the second term, put n = 2:
3*2 - 1 = 5.

Answer 3

Put the first term into the equation and then the second term and you will get your answers!
So if the first term is 1
Then 1= 3(1) -1 =2
And 2= 3(2) -1 =5
And so on so the 10th term would be:
10= 3(10) -1 = 29!!
Good luck

Answer 4

1st term is 3 x 1 - 1 = 2
2nd term is 3 x 2 - 1 = 5

Answer 5

its 2 and 5

Answer 6

Do it for yourself...put 1 instead of n, then put 2 instead of n.

3(1) -1 = 3-1 = 2
3(2) -1 = 6-1 = 5...the next would be 3x3 -1 = 9-1 = 8.
Hope that helps.

Answer 7

1st term is 3(1)-1
2nd term is 3(2)-1
so the terms will look like
3(1)-1, 3(2)-1, 3(3)-1 .................. 3n-1
u can solve each term
like
3(1)-1 =(3X1) -1 =2

Answer 8

1st = 2

2nd = 5

Answer 9

1.) 3x1-1=2
2.) 3x2-1=5
