mathematics - Buttons on an old non-scientific calculator are less sensitive



All 5 numbers are entered in an ascending order. These numbers are in an arithmetic progression. The value of the fifth number, i.e. the largest number, is less than 99. While adding these numbers, two plus(+) symbols were accidentally not entered due to the bad calculator, giving the sum as 71157.
And while finding the product of these numbers, two multiplication symbols were not typed, resulting in the mistaken product as 11698071.
In the places where + were entered correctly in the first operation, multiplication symbols were missing there in second operation and vice versa.




Find those 5 numbers, if the digit at the tens place of second number is 1.
