Question

Write an arithmatic progression whose first term is -3 common difference is 5

Answer 1

Step-by-step explanation:

-3, 2, 7, 12,...

a1 = - 3

d= 5

a2 = a+d = (-3)+5 = 2

a3 = a2+d = 2+5 = 7

Hope you get the idea how an a.p is formed, you need to add the common difference (5) to the first term(-3) to get the second term. This a.p will be infinite, which is indicated by the three dots (...) .

Answer 2

Answer:

-3, 2, 7, 12,........

Step-by-step explanation:

a = -3

a2 = a+d = -3+5 = 2

a3 = a+2d = -3+10 = 8

a4 = a+3d = -3+15 = 12
