Question

Which term of the A.P. 8,14,20,26........will be 72 more than its 41st term?

Answer 1

Answer: 53rd

Step-by-step explanation:

aₙ= 72+a41

aₙ=72+(a+40d)  = 72+248 =320

Now, aₙ= a+(n-1)d

320= 8+(n-1)x 6

8+6n-6=320

6n= 320-2

6n=318

n= 53

So, 53rd term of this A.P. will be 72 more than its 41st term.
