Question

Write the first six terms of the arithmetic sequence with the given first term, a,, and common difference, d.

a₁ = 250, d=-70

Answer 1

The formula

an = a+(n-1)d

when "An" represent the nth term of sequence given that a = -250 and d = 70

n=1

a1= -250 +(1-1)*70

a1 =-250 + 0

a1 =-250

n =2

a2 = -250 +(2-1)*70

a2 = -250 +70

a2 =-180

n =3

a3 = -250 + (3-1)*70

a3 = -250 +140

a3 = -110

n =4

a4 = -250 + (4-1)*70

a4 = -250 +210

a4 = -40

n =5

a5 = -250 + (5-1) *70

a5 = -250 +280

a5 = 30

n = 6

a6 = -250 +(6-1)*70

a6 = -250 + 350

a6 = 100

The answers are

-250,-180,-110,-40,30,100
