Question 3 (iii)
Write the first three terms of the AP’s, when a and d are as given below: a=√2,d=1√2
Open in App
Solution
Given that,
First term (a) = √2 and common difference (d) = 1√2
nth term of an AP, Tn = a + (n – 1) d ∴ Second term of the AP, T2=a+d=√2+1√2=2+1√2=3√2
Third term of the AP, T3=a+2d=√2+2√2=2+2√2=4√2
