Answer:
1. a7 = 45
2. a50 = 150
3. a99 = 485
1. the formula in determining the nth term of arithmetic sequence is
an=a+(n-1)d
Step-by-step explanation:
1. a= a + (n - 1 )d
a= 3 + (7 - 1) 7
a =3 + (6)7
a = 3 + 42
a= 45
2. a50 = 3 + (50 - 1) 3
a50 = 3 + (49)3
a50 = 3+147
a50 = 150
3. a99 = -5 + (99 - 1 )5
a99 = -5 + (98)5
a99 = -5 + 490
a99 = 485
