Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
 Kuna namba 3 ambazo ni namba za mfululizo. Pamoja zina jumla ya 18. Namba kubwa zaidi ni ipi?


### Response:
 Hebu tuchukue N = namba ndogo zaidi
N + 1 = namba inayofuata
N + 2 = namba kubwa zaidi
N + (N + 1) + (N + 2) = 18
3N + 3 = 18
3N = 15
N = 5, namba inayofuata = 6, namba kubwa zaidi = 7
Namba kubwa zaidi ni 7.
