terms of which the third
term is 12 and the
last term is 106
Find the 29th terme​

Answer 1

Answer:

64

Step-by-step explanation:

An = a+(n-1)d

12 = a+(3-1)d

12=a+2d

A=12-2d

A50=106

106=a+(50-1)d

106=12-2d+49d

106-12=47d

94=47d

D=94/47 = 2

A=12-2d

=12-2×2

=12-4=8

A29=a+(n-1)d

=8+(29-1)2

=8+28×2

=8+56 = 64

Answer 2

Therefore the answer = 64
