Question

Find the 8th term from the end of the Ap 7,10,13,........,184

Answer 1

Given in the AP, first term a = 7, common diff. d = (10 - 7) = 3,
last term L = 184 and n = 8 (from the end)

nth term from the end = {L - (n -1) d}

8th term from the end

= {184 - (8 - 1) 3}

= (184 - 7 * 3)

= 184 - 21

= 163 Ans.
