Question

What are the first four terms of the sequence represented by the expression 5+2n

Answer 1

subsitute n=1,n=2,n=3,=4 to get the firstt 4 terms

5+2(1)=5+2=7

5+2(2)=5+4=9

5+2(3)=5+6=11

5+2(4)=5+8=13



first 4 terms are 7,9,11,13

Answer 2

term 1, n = 1
5 + 2 × 1 = 5 + 2 = 7

term 2, n = 2
5 + 2 × 2 = 5 + 4 = 9

term 3, n = 3
5 + 2 × 3 = 5 + 6 = 11

term 4, n = 4
5 + 2 × 4 = 5 + 8 = 13

7, 9, 11, 13
