Q2 of 202 Page 9

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

a = 3, d = 5

A_n= a + (n – 1) d

248 = 3 + (n – 1) 5 = 3 + 5n – 5

248 = -2 + 5n

250 = 5n

n = 50

The nth term of an A.P. is 6n+2. Find the common difference.

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.

Which term of the A.P.is 0?

Which term of the A.P. is 254?
