it's from AP chapter . take a=75 and last term(l)= 25555 and d = 5. find n with formula
l= a+(n-1)d. where n is the number of terms. solve for n then you will get the answer

Hey Friend

here is your answer

a=75.
d=5
an=25555
so
an=a+(n-1)d

75+(n-1)5=25555

(n-1)5=25480

n-1=25480/5

n-1=5096

n=5096+1

n=5097

nishu8856: firm a starts producing 750 units and increase production by 20 units yearly.firm b starts producing 1950 units and deacreases production by 80 units yearly.assuming that change of production of both firms form AP find in what year both will produce same quantity

sheoranprateek: using a+(n-1) identity let a of 1st ap is 750 d is 20 and a of 2nd ap is 1950 d is 80 and n is same in both ap. then putting both ap equal I hope you understand and can do this question
