# Match the questions given under Column I with their appropriate answers given under the Column II. (a) Given: Here, , and Hence, the given numbers is in G.P with common ration 1/4

(a) (iii)

(b) Given: 2, 3, 5, 7

Here, a2 – a1 = 3 – 2 = 1

a3 – a2 = 5 – 3 = 2

a4 – a3 = 7 – 5 = 2

a2 – a1 a3 – a2

Hence, it is not in AP

Now, we will check the ratio , So, So, it is not a G.P

Hence, it is a sequence

(b) (ii)

(c) 13, 8, 3, -2, -7

Here, a2 – a1 = 8 – 13 = -5

a3 – a2 = 3 – 8 = -5

a4 – a3 = -2 – 3 = -5

a2 – a1= a3 – a2

Hence, it is an AP

(c) (i) Rate this question :
