Given :- AP = 1, 4, 7, 10 .... 118 here, we've to find the sum of the series. first term = a = 1 first term = a = 1common difference = d = 4 - 1 = 3 first term = a = 1common difference = d = 4 - 1 = 3An = 118 no. of terms isn't given so first of all, we've to find n general form of nth term = a + (n - 1)d a + (n - 1)d = 118 1 + (n - 1)3 = 118 1 + 3n - 3 = 118 3n = 118 + 3 - 1 3n = 120 n = 120/ ...

Answer:Here, first term (a) = 1 and common difference (d)=3So we can say that this sequence is in A.P100th of an A.P is given by: (a+99d)Therefore,100th term of…

Hi , 1, 4 , 7 , 10 , ... Here , a2 - a1 = 4 - 1 = 3 a3 - a2 = 7 - 4 = 3 Therefore , a2 - a1 = a3 - a2 = 3 common difference = d = 3 Therefore , given sequence is in A.P we know that , nth term = an = a + ( n -1 )d a = 1 , n = 20 , d = 3 a20 = 1 + ( 20 - 1 ) 3 = 1 + 19 ×3 = …

Jul 4, 2010 · The given sequence is 1 + 4 + 7 + 10 ..... uptu 22 terms. It is given that the given progression is arithmetic progression, so first term should 1 and second term should be 4.

Given that, 1 + 4 + 7 + 10 + ... + X = 287 If we consider the given AP (1 + 4 + ... + X) having n terms, then X is the nth term of the AP and the sum of the n terms is 287.

Mar 6, 2014 · Let there be n terms in the A.P. Thus, a = 1, d = 3 - 7zpvx6vv
