Question

the nth term of a sequence is n²+20
Work out the first three terms of the sequence

Answer 1

Answer:

  21, 24, 29

Step-by-step explanation:

Replace n with 1, 2, and 3, and do the arithmetic.

  first term = 1² +20 = 21

  second term = 2² +20 = 24

  third term = 3² +20 = 29

The first three terms are 21, 24, 29.
