Question 3 (ii) Write the first three terms of the AP’s, when a and d are as given below:
a = -5, d = - 3
Open in App
Solution
Given that,
First term (a) = - 5 and common difference (d) = - 3 nth term of an AP,Tn = a + (n – 1) d ∴Second term of the AP, T2=a+d=−5−3=−8 Third term of the AP, T3=a+2d=−5+2(−3)
= - 5 - 6 = -11
