Hey mate

Explanation:

Your upcoming term:-

201, 208 , 125 , _____???

Noticing the differences or relations between all the terms!!

201+(7) = 208

208+(7)= 215

215+(7)= 222

t(1)= 201

t(2)= 208

t(3)= 215

t(25)= ??

t(25)=

The above equation is an arithmetic progression with simple difference.

d= 208-201 = 215-208= 7

First term = a= 201

The sum of first an numbers of an AP with term a a & d :-

Sn= n/2{2a-(n+1)d}

Hence sum of first n numbers= 25 terms of an AP with term 201 and d = 7:-

S25= 25/2{2×201-(25-1)×7}

S25 = 33075

Therefore required term is

33075
