A person deposited Rs. 5000 in his saving account. The amount is set to increase by (110)th of itself every two years. What would be the maturity amount (in Rs.) of investment after the 2nd, 4th, 6th and 8th year respectively? Are these in AP?
5500, 6050, 6655, 7320.5, No
For the first two years, increment in the amount = Rs. 110×5000=Rs. 500
∴ The amount after 2 years would be Rs. 5500.
Similarly, the maturity amount after the 2nd, 4th, 6th and 8th years would be Rs. 5500, Rs. 6050, Rs. 6655, Rs.7320.5
Difference between first two consecutive terms = Rs.6050 - Rs.5500 = Rs.550
Difference between third and second consecutive terms = Rs. 6655 - Rs. 6050 = Rs. 605
Since a2–a1≠a3−a2=a4−a3, the maturity amounts do not form an AP.
