Question

25 term of the arithmetic sequence 1,2,3​

Answer 1

To find the "nth" term of an arithmetic sequence, start with the first term, a(1). Add to that the product of "n-1" and "d" (the difference between any two consecutive terms). For example, take the arithmetic sequence 3, 9, 15, 21, 27.... a(1) = 3. d = 6 (because the difference between consecutive terms is always 6.

Answer 2

Answer:

a=1, d= 2-1=1

25th term= a+24d

1+24×1=1+24=25

so, 25th term= 25.

Hope it helps!!!!!
