The first term in the sequence is 1.

Step-by-step explanation:

  • Given sequence is 2,3,4,5
  • where value of x is 0,1,2,3
  • an = a1 + (n-1)d
  • where an is nth therm
  • a1 is first term
  • (n-1) term position
  • d is common difference
  • an= 1 + (1-1)1
  • an = 1

  • therefore the first term in the sequence is 1
