The registration number for the thousandth consumer

EVALUATION

Here it is given that the first consumer of a gas agency was allotted with registration number as 1273688 and the second consumer as 1273689

So the given registration numbers are 1273688 , 1273689

So the numbers are in Arithmetic Progression

First term = a = 1273688

Common Difference = d = 1

Hence the registration number for the thousandth consumer

= 1000 th term of the AP

= a + ( 1000 - 1 ) d

= a + 999d

= 1273688 + ( 999 × 1 )

= 1273688 + 999

= 1274687
