Question

Find the 10th element of the sequence : 2,0,-2,-4...

Answer 1

tn= a+(n-1)d
t10 =2+(10-1)×-2
=2+(-9)×2
=2-18
= -15

therefore 10th element is -15

Answer 2

The 10th term of AP is - 14

Given:

The sequence: 2, 0, -2, -4…

To find:

10th term of AP

Solution:

Formula used:

The nth term of AP, a$_{n}$ = a + (n - 1)d

Given sequence is 2, 0, -2, -4

Where first term a = 2 and

common difference d = 0 - 2 = - 2

From the given formula, a$_{n}$ = a + (n - 1)d

10th term a₁₀ = 2 + (10 - 2) -2

= 2 + (8) (-2)

= 2 - 16

= -14

Therefore,

The 10th term of AP is - 14
