Question

Find the mth term of arithmetic progression 950,900 ,850,....​

Answer 1

a=950

d=-50

am=a+(m-1)d

am=950+(m-1)(-50)

am=950-50m+50

am=1000-50m

Answer 2

Hey Brainly user

Here goes your answer

the first term

a1=950

d=a2-a1

=900-950

=-50

we know that

aM=a1+(n-1)d

aM =950+(n-1)-50

Though they are two unknown quantities so we can't do anything

Note :I think so you have missed the n th term
