Question

The fourth term of an Appointment is 1 less than twice the second term,if the sixth term is 7 what is the first term?

Answer 1

Answer:

a+5d = 7 **

a+5d = 7 **a+ 3d = 2(a+d) - 1

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6d = 1

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6d = 1back in **

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6d = 1back in **a + 5=7

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6d = 1back in **a + 5=7a = 2

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6d = 1back in **a + 5=7a = 2the first term is 2

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6d = 1back in **a + 5=7a = 2the first term is 2check:

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6d = 1back in **a + 5=7a = 2the first term is 2check:sequence is 2,3,4,5,6,7,8, ...

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6d = 1back in **a + 5=7a = 2the first term is 2check:sequence is 2,3,4,5,6,7,8, ...Is the fourth term less than twice the second by 1 ? YES

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6d = 1back in **a + 5=7a = 2the first term is 2check:sequence is 2,3,4,5,6,7,8, ...Is the fourth term less than twice the second by 1 ? YESIs the 6th term equal to 7 ? YES

a+5d = 7 **a+ 3d = 2(a+d) - 1a + 3d = 2a + 2d - 1-a + d = -1 ***add ** and ***6d = 6d = 1back in **a + 5=7a = 2the first term is 2check:sequence is 2,3,4,5,6,7,8, ...Is the fourth term less than twice the second by 1 ? YESIs the 6th term equal to 7 ? YESAll is good.
