Question

if the first term(a)and the common difference (d) of a certain arithmetic progression(A.p.) is 4 and 0 respectively.find the first four terms of that A.P

Answer 1

a = 4
d = 0
1st term = 4
2nd term = a + d
= 4 + 0
= 4
3rd term = a+ 2d
= 4 + 2×0
= 4
....
AP will be 4,4,4,4......

Answer 2

first term,a = 4
common difference , d = 0
first four terms
a1 = a = 4
a2 = a+d = 4+0 = 4
23 = a +2d = 4 +2 *0 = 4+0 = 4
a4 = a+3d = 4   +3*0 = 4+0 =4

first four terms are
4,4,4 and 4
