What is the common difference (d) of the A.P. 410, 360, 310…..

What is the common difference (d) of the A.P. 2,-2,-6,-10….. ?

The common difference of a constant A.P. is ……

The sum of the 3rd and 7th terms of an A.P. is 6 and their product is 8. Find the 1st term (a) and the common difference (d) of the A.P.

l, m, n are three numbers in G.P., a is the first term of an A.P., whose l th, mth and nth terms are in H.P. If d is the common difference of the A.P.. prove that a = (m + 1)d.

Assertion (A) : Common difference of the A.P.: -5,-1,3,7, ……. Is 4. Reason (R ) : Common difference of the A.P.a,a+d, a+2d , …., is given by d =2^(nd) term -1^(st) term.

Find the common difference ( d) for an A.P., if t_(3) = 8 and t_(4) = 12 .

Fill in the blanks in the following table, given that a is the first term, d the common difference and a_(n) the nth term of the A.P.

Fill in the blanks in the following table, given that a is the first term, d the common difference and a_(n) the nth term of the A.P.
