Can someone help me with that question

a) The required terms are:

7,10,13,16,34

b) The required terms are:

-1,3,7,11,...35

Step-by-step explanation:

For each question we need to find the first 4 terms and the 10th term.

a) 3n + 4

Put n = 1, 2 ,3, 4 for first 4 terms, and 10 for 10th term

Put n = 1, 3(1)+4 = 3+4 = 7

Put n = 2 , 3(2)+4 = 6+4 = 10

Put n =3 , 3(3)+4 = 9+4 = 13

Put n = 4,  3(4) + 4 = 12+4 = 16

Now, Put n= 10 3(10)+4 = 30+4 = 34

So, the required terms are:

7,10,13,16,34

b) 4n -5

Put n = 1, 2 ,3, 4 for first 4 terms, and 10 for 10th term

Put n = 1, 4(1)-5 = 4 - 5 = -1

Put n = 2 , 4(2)-5 = 8-5 = 3

Put n =3 , 4(3)-5 = 12-5 = 7

Put n = 4,  4(4) -5 = 16-5 = 11

Now, Put n= 10 4(10)-5 = 40-5 = 35

So, the required terms are:

-1,3,7,11,...35

b) well because you get well
