Doubt in a code to calculate the growth of a tree

Question

I am having some difficulties to make this code below work. The statement of the exercise is this:

Utopian trees grow in a particular way in two cycles:

• Each spring doubles its size
• each summer grow a meter

If Laura plants a one meter utopian tree in late autumn, what would be her height after N cycles?

Some examples:

if N = 0, its height will be 1 meter (nothing has grown); si N = 1, its height will be 2 meters (doubled the height in spring); si N = 2, its height will be 3 meters (grew one meter more in summer); si N = 3, its height will be 6 meters (doubled the height in the next spring); And so ...

Write the function alturaArvoreUtopica, that uses an amount of growth cycles, and returns the resulting height of Laura’s tree.

There’s that code below:

function alturaArvoreUtopica(ciclos) {

const cicloInicial = 1;
const tamanhoInicial = 1;
const estacaoInicial = 0;

const estacoes = ['verao', 'primavera']
let tamanho = tamanhoInicial

for (let i = 0 + estacaoInicial; i < cicloInicial + estacaoInicial; i++) {
const estacao = estacoes[i % estacoes.length]

if (estacao === 'verao') tamanho += 1
if (estacao === 'primavera') tamanho *= 2
}

return tamanho
}

But it is presenting the following errors:

Your solution did not pass the tests Objectives that were not met: alturaArvoreUtopica makes comparisons against strings Results of the test: alturaArvoreUtopica(0) 2 == 1

I would like to know where I am going wrong in the code. Thanks in advance!
