Question

Hello i would like help and the answer to this please; what is the nth term rule of

Answer 1

Answer:

The nth term of the given sequence

$a_{n} = a_{n-1} + (2n-1)$

Step-by-step explanation:

Explanation:-

Given sequence  -5,-4,-1,4,11,20,31

a₀ = -5

a₁ = a₀ +1 = -5 +1   = -4

a₂ = a₁ + 3 = -4+3  = -1

a₃ = a₂ + 5 = -1 +5 = 4

a₄ = a₃ + 7 = 4 + 7  =11

a₅ = a₄ + 9 = 11+9 = 20

a₆ = a₅ + 11 =  20+11 = 31

a₇ = a₆ + 13 = 31 +13 =44

and so on

The nth term of the given sequence

$a_{n} = a_{n-1} + (2n-1)$
