Question

the sum of the first nth of the A.P -4,0,4,8,... is the same as the sum of the first nth terms of A .P 2,4,6,8,... find the value of n nth term of

Answer 1

Answer:

A.P=-4,0,4,8,12

Step-by-step explanation:

a=-4

d=0-(-4)

=4

therefore,=a+(n-1)d

=-4+(5-1)4

=-4+16

=12

and,A.P=2,4,6,8,12

a=2

d=4-2=2

therefore,=a+(n-1)d

=2+(5-1)2

=2+8

=10
