If the n-th nbsp-term in a pattern is 2n-2-5- then find the difference between 6-th nbsp-and 4-th nbsp-term-30101540

The correct option is D 40 Given that, n^th term is 2n^2+5 Therefore, 6^thterm = 2 × 6^2+5 nbsp;= 2 × 36+5=77 nbsp; 4^thterm = 2 × 4^2+5 = 2× 16+5=32+5 ...

Solution

The correct option is D 40
Given that, $n^{t h}$ term is $2 n^{2} + 5$

Therefore,

$6^{t h}$ term = $2 \times 6^{2} + 5 = 2 \times 36 + 5 = 77$

$4^{t h}$ term = $2 \times 4^{2} + 5 = 2 \times 16 + 5 = 32 + 5 = 37$

Difference $= 77 - 37 = 40$
