Given two A.P. `2,5,8,11...... T_(60)` and `3,5,79,......... T_(50)dot` Then find the number of terms which are identical.

Find the number of terms in the A.P 2,4,6,8,….,74

Find the number of terms in the A.P 3,6,9,12,….,111

No. of terms is the A.P. 2,5,8,11,…..110 is :

In an A.P. if S_1=T_1+T_2+T_3+.....+T_n(nod d)dotS_2=T_2+T_4+T_6+.........+T_(n-1) , then find the value of S_1//S_2 in terms of ndot

Consider two A.P. s: S_1:2,7,12 ,17 , 500t e r m s a n dS_1:1,8,15 ,22 , 300t e r m s Find the number of common term. Also find the last common term.

In the A.P. 3,5,7,…43 , find the middle term :

If A = ((5,4,3),(1,-7,9),(3,8,2)) then find the transpose of A.

In an A.P., the first term is 2 and the sum of first five terms is 5. Then the 31th term is
