### Instruction:
 Amy anapika mikate ya muffin kwa ajili ya marafiki zake. Jumatatu, anabeba muffin 1 shuleni kwa ajili ya kugawana. Kila siku kuanzia siku ya Jumanne, anabeba muffin moja zaidi shuleni kuliko alivyobeba siku iliyopita. Ikiwa Jumamosi anahesabu kuwa kuna muffin 7 zilizobaki, alipika muffin ngapi awali?


### Response:
 Jumanne, anabeba muffin 1 + 1 = <<1+1=2>>2.
Jumatano, anabeba muffin 2 + 1 = <<2+1=3>>3.
Alhamisi, anabeba muffin 3 + 1 = <<3+1=4>>4.
Ijumaa, anabeba muffin 4 + 1 = <<4+1=5>>5.
Jumla ya muffin anazobeba shuleni kugawana na marafiki zake ni 1 + 2 + 3 + 4 + 5 = <<1+2+3+4+5=15>>15.
Ameoka muffin 7 + 15 = <<7+15=22>>22.
