Question

4 Which of the following are APs ? If they form an AP, find the common difference d and write three more terms.
(xiii) √3,√6,√9,√12,---
(xiv) 1 Square, 3 Square, 5 Square,7 Square,---
(xv) 1 Square, 5 Square, 7 Square, 73,---​

Answer 1

Answer:

(xv)

Step-by-step explanation:

c.d=t2-t1=25-1=24

=t3-t2=49-25=24

Answer 2

Answer:

(xv) 1 Square, 5 Square, 7 Square, 73,---forms AP

${1}^{2} + {5}^{2} + {7}^{2} + 73.... \\ 1 + 25 + 49 + 73.... \\ d = 25 - 1 = 49 - 25 \\ 24 = 24 = d$

the next three terms of AP are :

97 , 121 , 145
