1.	Find the next three terms of the following sequence. (i) 8, 24, 72,… (ii) 5, 1, -3, … (iii) 1/4, 2/9, 3/16
Answer» (i) 216, 648, 1944 (This sequence is multiple of 3) Next three terms are 216, 648, 1944 (ii) Next three terms are -7, -11, -15 (adding -4 with each term) (iii) Next three terms are 4/25, 5/36 and 6/49 [using n/(n + 1)²]

Find the next three terms of the following sequence. (i) 8, 24, 72,… (ii) 5, 1, -3, … (iii) 1/4, 2/9, 3/16

Answer»

(i) 216, 648, 1944 (This sequence is multiple of 3)

Next three terms are 216, 648, 1944

(ii) Next three terms are -7, -11, -15

(adding -4 with each term)

(iii) Next three terms are 4/25, 5/36 and 6/49

[using n/(n + 1)²]
