Question

Nick recently started a landscaping company. He began with 3 clients. Thanks to word-of-mouth referrals, his clients double each month. How many clients will Nick have after one year?

Answer 1

Answer:

3+3*2^1+3*2^2+....+3*2^11

3[2^0+.....2^11]

by geometric progression

a=1 r=2

1*(2^12-1)/12-1=4096-1/11=372.27

answer : 3*327.27
