Question

if each term of an a.p isdouble the resulting sequance also in a.p write its first term ​

Answer 1

$\bf\large\underline\pink{Answer:-}$

The general form of an AP is a, a+d, a+2d,..... where a is the first term and d is the common difference If we double the terms, the new sequence would be 2a, 2a+2d, 2a+4d,...... We can observe that this sequence is also an AP First term is 2a Common difference is 2d nth term= 2a+(n-1)2d = 2[a+(n-1)d]
