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
