Expert Solution
Step 1

Solution ) in geometric sequence 

Term is given  by 

an = a1rx -1

r = geometric ratio , a1 = first term

In part B

Second term is 10

n = 2

10 = a1r2-1

10 = a1r    .......... (1)

4th term is 40

40 = a1r4 - 1

40 = a1r3       ..............(2)

equation (2) ÷ equation (1)

40/10 = a1r3 / a1r

4 = r2

[ r = 2 ]
