For an A.P. if a= 100, d = 100, what is t_(10) ?

In an AP,If a =-10,n=6 and a_(n)=10, then find the value of d.

10,5,0….are in A.P then d=

If for an A.P., a= 10.5 , d= 0 , dn = 101, then what is the value of t_(n) ?

The number of terms of an A.P. is even; the sum of the odd terms is 24, and of the even terms is 30, and the last term exceeds the first by 21/2 then the number of terms in the series is 8 b. 4 c. 6 d. 10

In a AP of 50 terms the sum of first 10 terms is 210 and the sum of last 15 terms is 2565. Then find the AP

The first term of A.P. is 5, the last is 45 and their sum is 400. If the number of terms is n and d is the common differences , then ((n)/(d)) is equal to :

The first term of A.P. is 5, the last is 45 and their sum is 400. If the number of terms is n and d is the common differences , then ((n)/(d)) is equal to :

The 6^(th) term of an A.P is -10 and its 10^(th) term is - 26 .Determine the 13^(th) term of the A.P .

The sequence -10,-6,-2,2,….. a)is an A.P, Reason d=-16 b)is an A.P, Reason d=-4 c)is an A.P, Reason d= 4 d)is not an A.P.
