Q3 of 105 Page 139

Find the respective terms for the following APs.

a1 = 4; a6 = 6. Find a2, a3, a4, a5

Given that a1 = 4

And a6 = 6


a6 = a1 + (6-1)d


6 = 4 + 5d


D = 0.4


To find a2:


a2 = a1 + (2-1)d


= 4 + 0.4


= 4.4


To find a3:


a3 = a1 + (3-1)d


= 4 + 2×0.4


= 4.8


To find a4:


a4 = a1 + (4-1)d


= 4 + 3×0.4


= 5.2


To find a5:


a5 = a1 + (5-1)d


= 4 + 4×0.4


= 5.6
