Answer 1

Step-by-step explanation:

we have to find 11 term from last therefore

last term of ap will become as first term and then the ap wii be

253,248,243......3

a=253 d=248-253=-5 n=11

a^n=253+(11-1)×-5

=253-50

=203 ans

Answer 2

Answer:

Step-by-step explanation:

let us take the last term as A = 253

common difference d = 5

which when considered from last is -5

nth term = A + ( n-1) d

              = 253 + ( 11-1) (-5)

              = 253 + (10 )(-5)

              = 253 - 50

              = 203

directly u may even use this formula

nth term from last = last term - (n-1) d
