Question

geometric progression​

Answer 1

Answer:

Step-by-step explanation:

actually the terms are not in geometric progression but they are in arithemetic progression

if we observe the common differenece between the terms

5/2-2=1/2

3-5/2=1/2

so the terms are in Arithmetic progression

so the nth term =a+(n-1)d

d=1/2

a=2

n=12

so

12th term=2+(12-1)*1/2

=2+11/2

=15/2

Answer 2

Answer:

for the question first term a=2

common ratio r=5/4

an=a.r^n-1

a12=2*5/4^12-1

a12=2*5/4^11
