2,6,10,14....... find the 15th term
<pre><font size = 4 color = "indigo"><b>
{{{6-2=4}}}, {{{10-6=4}}}, {{{14-10=4}}}

So {{{d=4}}}, {{{a[1]=2}}}

{{{a[n]=a[1]+(n-1)d}}}

{{{a[15]=2+(15-1)(4)}}}

{{{a[15]=2+(14)(4)}}}

{{{a[15]=2+56}}}

{{{a[15]=58}}}

Checking:

2,6,10,14,18,22,26,30,34,38,42,46,50,54,58
