Q2 of 202 Page 9

Which term of the A.P.is 0?

a = 84, d = -4

A_n= a + (n – 1) d

0 = 84 + (n – 1) -4

0 = 84 – 4n + 4

0 = 88 – 4n

n = 22

Find:

(i) 10^th term of the A.P.

(ii) 18^th term of the A.P.

(iii) n^th term of the A.P.

(iv) 10^th term of the A.P.

(v) 8^th term of the A.P.

(vi) 11^th term of the A.P.

(vii) 9^th term of the A.P.

(i) Which term of the A.P. is 248?

Which term of the A.P. is 254?

Which term of the A.P. is 420?
