Question

If the nth term of the progression is (4n-10) show that it is an ap find its (1)first term (2) common difference (3) 16 th term

Answer 1

1st term =-6

common difference =4

16th term=22

Step-by-step explanation:

Here,

nth term =4n-10

therefore 1st term =4×1-10

=-6

2nd term = 4×2 -10

=-2

therefore , common difference d =2nd term -1st term

=-2 - (-6)

=4

Now, 16 th term =4×16-10

=32-10

22
