Question

write the first 4 term of AP when the first term is1•25 and common difference is -•25​

Answer 1

a = 1.25

d = -0.25

AP for first four terms of AP are

a¹ = a + d

= 1.25 + (-0.25)

= 1

a² = a¹ + d

= 1 - 0.25

= 0.75

a³ = a² + d

= 0.75 - 0.25

= 0.50

a⁴ = a³ + d

= 0.50 - 0.25

= 0.25
