Question

for each sequence, find the first 4 term and the 10th term 2nsquard (algbra) pls can sm1 answer me plis

Answer 1

2, 8, 18, 32.

10th term = 200.

Explanation:

The first 4 terms of 2n^2 are

2(1)^2, 2(2)^2, 2(3)^2, 2(4)^2

= 2, 2*4, 2*9, 2*16

= 2, 8, 18, 32.

The 10th term = 2(10)^2

= 200.

Answer 2

see explanation

Explanation:

To find the terms of the sequence substitute n = 1, 2, 3, 4, 10 into the rule.

n = 1 → 2(1)² = 2(1) = 2

n = 2 → 2(2)² = 2(4) = 8

n = 3 → 2(3)² = 2(9) = 18

n = 4 → 2(4)² = 2(16) = 32

n = 10 → 2(10)² = 2(100) = 200

The first 4 terms are 1, 8, 18, 32 and the 10 th term is 200
