Question 2 (v)
Write first four terms of the A.P. when the first term "a" and the common difference "d" are given as follows.
(v) a=−1.25,d=−0.25
Given,a=−1.25 and d=−0.25
Let the group of numbers be a1,a2,a3,a4,a5, …
a1=a=−1.25a2=a1+d=−1.25−0.25=−1.50a3=a2+d=−1.50−0.25=−1.75a4=a3+d=−1.75−0.25=−2.00
Clearly, the series is 1.25, - 1.50, - 1.75, - 2.00, ……..
Hence, the first four terms of this A.P. are - 1.25, - 1.50, - 1.75 and - 2.00.
