Question

Find the first four terms of the sequence represented by the expression 4n+3

Answer 1

`T_n = 4n + 3`

To find the first term, we replace n = 1, to find the second term, we replace n = 2 and so on.


`T_1 = 4(1) + 3 = 7`


`T_2 = 4(2) + 3 = 11`


`T_3 = 4(3) + 3 = 15`


`T_4 = 4(4) + 3 = 19`

Answer: The first 4 terms are 7, 11, 15 and 19

Answer 2

First term is found by putting n = 1:
4(1)+3 = 7
Next term = 4(2)+3 = 11

First 5 terms are 7, 11, 15 , 19
