Question

Write first four term of AP whose first term =-1.25 andthe common difference=-0.25

Answer 1

Answer:

-1.25,-1.50,-1.75,-2.0,-2.25

Step-by-step explanation:

Write first four term of AP whose first term =-1.25 and the common difference=- 0.25

Given :

$a = - 1.25 \\ \\ d = - 0.25$

nth term of an A.P.

$a_n = a + (n - 1)d \\ \\ a_2 = a + d \\ \\ = - 1.25 - 0.25 \\ \\ = - 1.50 \\ \\ a_3= a + 2d \\ \\ = - 1.25 - 2(0.25 )\\ \\ = - 1.75 \\ \\ a_4 = a +3 d \\ \\ = - 1.25 - 3(0.25) \\ \\ = - 2.00 \\ \\a_5 = a +4 d \\ \\ = - 1.25 - 4(0.25) \\ \\ = - 2.25$

Hope it helps you.
