Question

Find the 21st term of AP whose first two terms are -3 and
4

Answer 1

Answer:

21st term = 137

Step-by-step explanation:

a = -3

2nd term = a + d

4 = -3 + d

d = 7

a = -3      d = 7      n = 21

21st term = a + d(n - 1)

               = -3 + 7(20)

               = -3 + 140

21st term = 137
