WebSolution. Verified by Toppr. We know the sum of n terms of an A.P with first term a and the common difference d is: S n= 2n[2a+(n−1)d] Here, it is given that the first term is a=3, common difference is d=7−3=4 and n= 25, therefore, the sum is: S 25= 225[(2×3)+(25−1)4]= 225[6+(24×4)]= 225(6+96)= 225×102=25×51=1275. Hence, the sum is 1275. Web21 Jan 2024 · Now, since we have 100 numbers each of which consists of 2 digits, we, therefore, have: 2 x 100 = 200 individual digits. The average value of each digit is: 1+2+3+4+5+6+7+8+9 =45/10 =4.5. 200 x 4.5 = 900 - this is the sum of all numbers from 1 to 100. And to this add the sum of all numbers from 100 to 110 inclusive =57.
