Question

What Is The Recursive Rule For The Sequence? 1.2, 0.4, -0.4, – 1.2, -2,

Answer 1

`\boxed{\bold{a_n = a_(n-1) -0.8}}`

Step-by-step explanation:

Sequence: 1.2, 0.4, -0.4, – 1.2, -2,...

See that with every next term, the integers are decreasing by 0.8

• So, common difference (d) = -0.8

recursive formula :
`\sf a_n = a_(n-1) +d`

`\bold a_1 = 1.2,`
`\sf a_n = a_(n-1) + (-0.8)`
