Question

Find the 60th term of a ep 8, 10, 12 if it has a total of 60 terms and hence find the sum of its last 10 terms

Answer 1

sorry but take a look at this

For unique solution a1/a2 should not be equal to b1/b2 ...so 4/k =1/1

if we cross multiply them we get k is equal to 4...

Bt as the question says it is a unique solution so we'll write it as k should bt be equal to 4

hope it helps you
